Per discussion with @hammadj, @topocount, and @wchargin, we are planning
to have the frontend2 system use react-admin at the top level. Per
investigation by @topocount, react-admin conflicts with the older
version of react-router that we use.
As such, this commit wildly simplifies the homepage2 system so we no
longer have any routing, and instead we just statically render the
index.html file. We also removed the `Assets` type, not because we are
sure we don't need it, but because we didn't want to debug it while we
were all pairing. @wchargin offered to fix it up later.
Test plan:
- run `yarn start2 --instance=PATH` and observe that the "Under
Construction" message displays, along with console messages showing that
data loaded successfully.
- run `yarn build2` and copy files from `build2` into the root of a cli2
instance. Run an http server in that instance, and observe that the
frontend displays properly per instructions above.

This modifies the frontend2 so that we can load real data from cli2
instances, including:
- the root `sourcecred.json` config
- files inside the `config/` directory
- files inside the `output/` directory
This works both for the dev server and the compiled output.
In the case of the dev server, it's now necessary to provide the path to
the cli2 instance you're developing against. You can pass this via the
`--instance` argument, as in `yarn start2 --instance=/path/`, or via
the `$SOURCECRED_DEV_INSTANCE` environment variable (recommended). If
neither is provided, or if that path doesn't look like a valid instance,
an error is thrown.
In the case of the built output, given a valid sc2 instance, you can set
it up via the following:
```
cp -r build2/favicon.png build2/index.html build2/static $INSTANCE
```
Then spin up a simple http server in the $INSTANCE.
You can look at console messages in the frontend to verify that the
instance is working (note it expects to see a discourse config file, not
a GitHub config file as was used in some previous examples).
Test plan:
Setup an example Discourse instance, and then turn on the server via
`yarn start2 --instance=PATH`,
`SOURCECRED_DEV_INSTANCE=path yarn start2`,
and by manually copying in the built outputs using the instructions
above.
In each case, you can load the homepage and check the console to see
that assets loaded successfully.
The frontend build system has a bunch of logic for loading in the list
of projectIds and including them in the build. Fortunately, in
frontend2, we won't need this. This commit simply removes all that
logic.
Test plan: Grepping for `projectIds` finds no hits inside the frontend2
system, except for a comment noting that we'll be able to remove an
argument once the transition is complete. `yarn start2` still works as
expected.
The cli2 ("instance") system has a foundationally different assumption
about how the frontend works: rather than having a unified frontend that
abstracts over many separate SourceCred projects, we'll have a single
frontend entry per instance. This means we no longer need (for example)
to make project IDs available at build time.
Our frontend setup and server side rendering is pretty complex, so
rather than rebuild it from scratch, I'm going to fork it into an
independent copy and then change it to suit our needs.
To start here, I've duplicated the `src/homepage` directory into
`src/homepage2`, duplicated the webpack config to
`config/webpack.config.web2.js`, and duplicated the paths and
package.json scripts.
Test plan:
Run `yarn start2` and it will start an identical frontend, using the
duplicated directory. Run `yarn build2` and it will build a viable
frontend into the `build2` directory. `build2` is gitignored.
