Integrate the identity plugin (#1385)
This commit integrates the identity plugin, which was created in #1384.
It does this by adding explicit identity fields to the project
configuration, which are then applied when loading the graph in
`api/load.js`.

The actual integration is quite straightforward.

Test plan: The underlying logic is thoroughly tested; I added one new
test case to verify that it is integrated properly. Since the project
compat has changed, I've updated all the snapshots. Prior to merging
this PR, I will produce one "integration test", using this code to do
identity resolution for a real project (i.e. on the SourceCred instance
itself).

scores command no longer assumes GitHub plugin (#1372)
Previously, the `sourcecred scores` command assumed that all users are
GitHub users, and assigned users an id based on their GitHub login.

Now, the command returns information on all users, regardless of which
plugin provided them. As such, we need to identify users differently.
Instead of a string id, they now have an array of address parts. That
array contains all of the parts of their corresponding node address.

For example, the GitHub user `@Beanow` would correspond to the address
array `["sourcecred", "github", "USERLIKE", "USER", "Beanow"]`

As a general convention, the first two components of any node's address
contain information about the plugin that owns that node. The first
component is the owner of the plugin, and the second is the name of the
plugin. Afterwards, the plugin may represent nodes in whatever manner it
sees fit.

Thanks to @Beanow and @vsoch for some feedback and discussion on this
design.

Test plan: Snapshots have been updated. `yarn test` passes.

Replace TimelineCredConfig with array of plugins (#1367)
The PluginDeclaration has all of the information we need to configure
TimelineCred: it knows all the node and edge types, as well as which
node types are user (or scoring) node types.

Therefore, we can replace the ad-hoc config object with a simple array
of plugin declarations. Since the plugins will be saved as part of the
TimelineCred, it means the UI can configure to only show information for
plugins that are actually in scope.

Test plan: `yarn test` passes, and the prototype still works. Snapshots
updated.

Enable multiple scoring node types (#1361)
This updates the cred computation logic so that we can have multiple
"scoring node types".

Context: Currently, we designate a single node type (GitHub users) as
the scoring node type, and normalize so that all users have 1000 score
in total.

This commit updates the pipeline to admit using more than one prefix for
scoring, meaning that we could have GitHub users, Discourse users, and
more, and still have all users sum to 1000 score.

We will still need to update the frontend so that it will have a user
pane which aggregates across all users.

Test plan: Unit tests updated. `yarn test` passes.

test: fix `example-github-load` snapshot test (#1359)
Summary:
Generated with `./scripts/update_snapshots.sh` (with #1360 patched in).
This fixes failures introduced in #1358.

Test Plan:
Running `yarn test --full` now passes. Inspecting the diff (after piping
the old and new snapshots to `jq -S .`) shows that this includes only
additions, which seems appropriate given the precipitating change.

Change TimelineCred filtering strategy (#1358)
This changes how TimelineCred filtering works. Instead of using the
filterTimelineCred module, which includes all nodes matching
filterPrefixes, we now take all nodes matching scorePrefixes and
additionally the top `k` nodes for every other type.

This ensures that we will have the top comments, pull requests, issues,
etc in the UI, without needing to take every single comment or PR or
issue.

Concurrently, the UI is updated so that every type is included in the
filter dropdown.

CHANGELOG has been updated, since this is user facing.

Test plan: `yarn test` passes, snapshots are updated, and I also tested
the UI manually.

hide `filterTimelineCred` (#1357)
TimelineCred computation is implemented as follows:
- Compute Distribution
- Filter it down to specified node types
- Wrap the filtered results into a TimelineCred

I want to change how the filtering works. The new filtering logic will
depend on logic we've already implemented in TimelineCred; therefore
filtering should be done on the TimelineCred object and not separately.
Specifically, I want to be able to filter down to the highest-scored
nodes by type (dependent on the type).

As a first step, I've refactored the interface to TimelineCred so that
the filtering is an implementation detail, i.e. the TimelineCred
constructor doesn't expect objects defined in `filterTimelineCred`.

Test plan: `yarn test` passes after a snapshot update.

timeline cred config is stored in JSON (#1356)
This modifies the TimelineCred serialization so that it includes the
CredConfig in the JSON. This means that it's easier to coordinate which
plugins and types are in scope, as the data itself can contain that
information.

Rather than define a new hand-rolled serializer, I just passed the
config directly through for stringification. Unit tests verify that this
still works (round-trip serialization is tested). As an added sanity
check, I generated a new small `cred.json`, and inspected the file via
`cat` to ensure that it's still legible text, and isn't interpreted as a
binary file due to the `NUL` bytes in node addresses.

Every client that previously depended on the `DEFAULT_CRED_CONFIG` now
properly gets its cred configuration from the JSON.

Test plan: Unit tests for serialization already exist. Generated a fresh
`cred.json` file and tested the frontend with it. Also,
`yarn test --full` passes.

Dandelion Mané d5a1ca30b4 Fixup project for move of example repos
I moved sourcecred/example-git{,hub} to the @sourcecred-test org.

This commit fixes the build given that move.

I've realized that in #1233 I in-advertently made some Git tests that
depend on a snapshot un-updateable. I'm going to compound on that slight
technical debt by skipping the tests that depended on that snapshot. I
recognize and accept that I'll need to pay this down when I resuscitate
the git plugin.

Test plan: `yarn test --full`.

Dandelion Mané c15e97b4d4 change the world: track projects not repos
This commit swaps usage over to the new implementation of `cli/load`
(the one that wraps `api/load`) and makes changes throughout the project
to accomodate that we now track instances by Project rather than by
RepoId.

Test plan: Unit tests updated; run `yarn test --full`. Also, for safety:
actually load a project (by whole org, why not) and verify that the
frontend still works.

add `sourcecred/scores` (#1223)
The scores are lightly processed from their internal representation.
Example usage:

```
$ yarn backend;
$ node bin/sourcecred.js load sourcecred/sourcecred
$ node bin/sourcecred.js scores sourcecred/sourcecred > scores.json
```

The data structure is as follows:

```js
export type NodeOutput = {|
  +id: string,
  +totalCred: number,
  +intervalCred: $ReadOnlyArray<number>,
|};

export type ScoreOutput = Compatible<{|
  +users: $ReadOnlyArray<NodeOutput>,
  +intervals: $ReadOnlyArray<Interval>,
|}>;
```

Test plan: I added sharness tests at `sharness/test_cli_scores.t`.
In the past, we've used javascript tests for CLI commands. However,
those are pretty time-consuming to write, and are less robust than
simply running the command from bash. Check the snapshot for a sense of
what the new data format looks like. Also, the snapshot updater now
updates this snapshot too.

Relevant for #1047.
Thanks to @Beanow for feedback on the output format and design.
Thanks to @wchargin for help in code review.

Dandelion Mané 4ba9fe3a8c fix sharness/test_build_static_site.t
This fixes a build error in test_build_static_site.t.
It's been masked by a lot of ENOMEM issues I've been having in the full
build, so a few failures had actually had a chance to accrue:

- Fixes an issue wherein loading the sourcecred/example-git repo would
error (on failure to normalize scores, because there was no user
activity). Fixed it pretty crudely by adding an issue to that
repository.

- Fixes an issue where a deprecation warning caused the
build_static_site build to fail. We now permit that particular warning.

- Updates the example load snapshot.

Test plan: `yarn test --full` passes once again.

Dandelion Mané 7d26c196f2 Disable the Git plugin
This commit disables the Git plugin by removing it from the default list
of plugins to load, or to display in the frontend.

Rationale: The git plugin doesn't currently add very much to cred
quality. Git commits have edges to their parent, which isn't a very
meaningful relationship for cred purposes. We'll want to re-enable the
Git plugin once we're ready to support e.g. file and directory level
cred tracking.

I've skipped a block of tests around the git analysisAdapter. (I intend
to deprecate the analysisAdapters, so skipping the tests seemed
preferrable to updating them). I also updated our sharness test for
catching test files without a proper describe block, so that it won't
error on skipped blocks.

Test plan: `yarn test --full` passes. Loading a new repository and
inspecting it in the frontend gives consistent results. There are no
references to Git plugin weights in the frontend, now that corresponding
nodes are not available.

Dandelion Mané e47c9b3aba graph: add node and edge timestamps

Dandelion Mané 6c5e8b70d6 graph: add descriptions
This updates the graph `Node` type to include a string description.

The description should be a brief (ideally oneline) string giving
context on what the node is. All planned frontends will support
markdown, so linking to context (e.g. linking to the issue corresponding
to an ISSUE type node) is supported.

This commit updates the Git and GitHub plugins to use the new
description field.

Test plan: `yarn test --full` passes, and I've inspected snapshots and
made sure they look reasonable.

Dandelion Mané 02a8e02922 graph: add support for dangling edges
This commit modifies the Graph class so that it permits dangling edges;
that is to say, edges whose src or dst are not present in the graph.
Dangling edges may be directly added to the graph, or existing edges may
become dangling if their src or dst is removed.

This change is prerequisite to #1136; if we require that nodes have
metadata, we should also make it possible to add edges to nodes that
don't yet exist, as the plugin creating an edge may not have access to
the full metadata needed to add the node.

To support this change, there is now an `isDanglingEdge` method on the
graph, which reports whether or not the edge is dangling. Also,
`Graph.edges` requires that the client make an explicit choice on
whether dangling edges are desired. This ensures that we do not
accidentally include dangling edges in a case where they are
inappropriate (e.g. creating a Markov chain) or accidentally discard
dangling edges when they are needed (e.g. when merging or serializing).

The Graph's invariant checker has been updated to reflect the new
semantics.

The Graph compat version has been bumped, since this is a break in
backwards compatibility.

Note that this commit does not change the behavior of any plugins; that
is to say, no plugins create dangling edges (yet).

Test plan: The advanced graph test case has been updated to include
dangling edges. The tests for Graph, PagerankGraph, and
GraphToMarkovChain have been updated. `yarn test --full` passes.

Add GitHub reaction timestamps (#1185)

Dandelion Mané 4b1763ebc6 Discard mentionsAuthorReference
I added `mentionsAuthorReference` based on an untested hypothesis that
they would be useful. With the passage of time, I've never seen any
evidence that they actually improve cred socres (their impact seems
negligible), and they add complexity.

In the future, "go-fishing" style heuristics like this should not merge
unless they are of clearly demonstrated value. Also, it would be better
to add stuff like this via a standalone plugin rather than in the core
GitHub logic.

Undoes #806.

Test plan: `yarn test`

Dandelion Mané 67baacd862 cli load: save graph, not pagerank or timestampMap
As of the timeline cred work, I'm shifting emphasis away from raw
PageRank results, in favor of timeline pagerank results. As such,
there's no need to have load save the regular pagerank results on
creation.

As of #1136, there will be no need for timestampMap, as that data will
be present directly in the graph. As the timeline cred UI will depend on
the full graph for analysis, let's save the graph instead.

Test plan: `yarn test` and snapshot inspection.

Add a GitHub Commit node type (#1175)
At present, the Git commit node type lives in a strange state of shared
responsibility between GitHub and Git. The Git plugin is nominally
responsible for it, but its render method tries to show a hyperlink to
GitHub -- which is awkward for many reasons, including that the same Git
commit could have multiple hyperlinks on GitHub.

This commit resolves that issue by separating the existing commit type
into two: the Git Commit type, which is owned by the Git plugin and
doesn't have hyperlinks or any fancy GitHub metadata, and the GitHub
Commit, which is owned by the GitHub plugin, corresponds to a unique
database id in GitHub, and has a corresponding GitHub url.

The two commits are connected by a CorrespondsToCommit edge type, which
links from the GitHub commit to the corresponding Git commit.

This is necessary for #1136, as if we want to make descriptions a part
of the graph payload, we need for descriptions to be unique for a given
address--and descriptions are only unique if we identifiy each GitHub
commit pointer as a separate address.

Test plan: The unit testing in this part of the codebase is light, so I
verified that the frontend work as expected for `sourcecred/sourcecred`
and `sourcecred/research`. The new node type and edge type appear
properly in the UI, the GitHub commits are connected to their Git
counterparts, etc.

Aggregate timestamp information on sourcecred load (#1162)
This modifies `sourcecred load` so that it saves timestamp information
for all of the loaded plugins in a single aggregated map.

This is quite convenient, as it saves consumers of timestamp information
from needing to worry about the (rather hacky) implementation whereby
the data is fed from each adapter. Instead, consumers can just load the
timestamp map. This will also make it much easier to use timestamp info
in the research codebase.

Test plan: The timestampMap module has testing around generating the map
from the adapter and nodes, writing it, and reading it.

I haven't added any testing to the `load` CLI command. I think it would
be redundant as the updated snapshot test reveals that the map is
getting serialized properly.

Tests pass, and I have inspected the snapshot

Add createdAt timestamp tracking to GitHub (#1152)
Updates github schema to include createdAt timestamps, and then updates
the RelationalView to provide those timestamps as MsSinceEpoch.

I added createdAt timestamps to Repos, Issues, Pulls, Reviews, and
Comments, as these correspond to GitHub graph nodes where I think
time-based filtering is relevant. I didn't add them to Users, Reactions,
or Commits. Reactions, because they correspond to edges not nodes. (We
could consider doing the time filtering on edges too, but I'd rather
keep it simple for now.) Commits, because they're owned by a different
plugin. Users, because... in a certain sense the user identity is
timeless, the time factoring is mostly so we can evaluate how users'
cred varies over time.

Anyway, it will be easy to add more fields later if we need them.

Test plan:
- Inspect snapshot changes
- Ran `yarn test --full`
  - Its only failure is pre-existing, per #1151

Thanks to @s-ben for some motivation and discussion about this change.

Automatically run pagerank on `sourcecred load` (#1115)
This commit updates the `sourcecred load` command so that it also
automatically runs PageRank on completion.

The implementation is slightly hacky, in that it prints two sets of
task status headers/footers to console, for reasons described in a
comment in the source code. The user-visible effect of this hack can
be seen below:

```
❯ node bin/sourcecred.js load sourcecred/example-github

Starting tasks
  GO   load-git
  GO   load-github
 DONE  load-github
 DONE  load-git

Overview
Final result:  SUCCESS

Starting tasks
  GO   run-pagerank
 DONE  run-pagerank

Overview
Final result:  SUCCESS
```

It would be good to clean this up, but for now I think it's acceptable.

Note that it is not safe to assume that a PagerankGraph always exists
for repos that are included in the RepoIdRegistry. The repo gets added
to the registry before the pagerank task runs. Consumers that are
loading the `PagerankGraph` can just check that the file exists, though.

Test plan: I've added unit tests that verify that the right tasks are
generated. Most importantly, the snapshot of the results of `sourcecred
load` now include a snapshotted pagerank graph.
(The snapshot was updated via `UPDATE_SNAPSHOT=1 yarn test --full`.)

Further progress on #967.

Update github example data (#1077)
Updating github example data with support
for 🚀 and 👀 reaction types.

This follows #1068 and @decentralion updating
the archived repo with the new reaction types.

`src/plugins/github/fetchGithubRepoTest.sh -u`
(as @decentralion suggested) updated `example-github.json`

`yarn unit` caught two tests with failing snapshot
tests (`createGraph.test` and `relationalView.test`), so
I updated those with `yarn unit -u`

`yarn test -full` caught a failing snapshot test
at `sharness-full`, resolved by updating the
snapshot in `view.json.gz` with
 `UPDATE_SNAPSHOT=1 yarn test --full`.
Thanks to @wchargin for the [explanation] on how
to resolve that issue.

[explanation]: https://github.com/sourcecred/sourcecred/pull/1077#pullrequestreview-196805017

**Test Plan:**
`yarn test --full` is passing.

Additionally, the commands:
```sh
    filepath="./sharness/__snapshots__/example-github-load/data/sourcecred/example-github/github/view.json.gz" &&
    [ -f "${filepath}" ] &&  # sanity check
    diff -u \
        <(git show "HEAD:${filepath}" | gzip -d | jq .) \
        <(gzip -dc "${filepath}" | jq .) \
        ;

core: allow repo ID registry to store metadata (#1003)
Summary:
Our registry was defined to simply be a list of IDs. This is
insufficiently flexible; we want to be able to annotate these IDs with,
e.g., last-updated times (#989). This commit wraps the entries in a
simple object, updating clients appropriately.

Test Plan:

  - Run `node ./bin/sourcecred.js load sourcecred/example-github` with a
    repository registry in the old format, and note that it errors
    appropriately.
  - Run `yarn build` with a repository registry in the old format, and
    note that it errors (“Compat mismatch”).
  - Delete the old registry and re-run the `load` command. Note that it
    runs successfully and outputs a registry. Run `yarn build`; note
    that this works.
  - Load data for two repositories. Run `yarn start`. Note that the list
    of prototypes still works, and that you can navigate to and render
    attributions for individual project pages.
  - Verify that `yarn test --full` passes.
