server: partly fix config entry replication issue that prevents replication in some circumstances (#12307)
There are some cross-config-entry relationships that are enforced during
"graph validation" at persistence time that are required to be
maintained. This means that config entries may form a digraph at times.

Config entry replication procedes in a particular sorted order by kind
and name.

Occasionally there are some fixups to these digraphs that end up
replicating in the wrong order and replicating the leaves
(ingress-gateway) before the roots (service-defaults) leading to
replication halting due to a graph validation error related to things
like mismatched service protocol requirements.

This PR changes replication to give each computed change (upsert/delete)
a fair shot at being applied before deciding to terminate that round of
replication in error. In the case where we've simply tried to do the
operations in the wrong order at least ONE of the outstanding requests
will complete in the right order, leading the subsequent round to have
fewer operations to do, with a smaller likelihood of graph validation
errors.

This does not address all scenarios, but for scenarios where the edits
are being applied in the wrong order this should avoid replication
halting.

Fixes #9319

The scenario that is NOT ADDRESSED by this PR is as follows:

1. create: service-defaults: name=new-web, protocol=http
2. create: service-defaults: name=old-web, protocol=http
3. create: service-resolver: name=old-web, redirect-to=new-web
4. delete: service-resolver: name=old-web
5. update: service-defaults: name=old-web, protocol=grpc
6. update: service-defaults: name=new-web, protocol=grpc
7. create: service-resolver: name=old-web, redirect-to=new-web

If you shutdown dc2 just before (4) and turn it back on after (7)
replication is impossible as there is no single edit you can make to
make forward progress.

* docs/nia: new configuration for services source_input

* reword filter and cts_user_defined_meta

Co-authored-by: trujillo-adam <47586768+trujillo-adam@users.noreply.github.com>

* Update service block config to table format

Co-authored-by: trujillo-adam <47586768+trujillo-adam@users.noreply.github.com>

* Remove deprecated driver.working_dir (#11831)

* Deprecate workspace_prefix for now workspaces.prefix (#11836)

* docs/nia: new config field names for services condition/source_input (#11896)

* docs/nia: new config field `names` for services condition/source_input

* Remove language about 'default condition' and services condition relation to services list

Context:
 - Added a new `names` field to condition/source_input "services"
 - `names` or `regexp` must be configured for condition/source_input "services"

This therefore:
 - Removed relationship between condition/source_input "services" and
 task.services list
 - Removed concept of "default condition" i.e. condition "services" must be
 configured with `names` or `regexp`, there is no meaningful unconfigured default

Change: remove language regarding "default condition" and relationship with services list

* docs/nia: Update paramters to table format

Changes from a bulleted list to a table. Also adds the possible response codes
and fixes the update example response to include the inspect object.

* docs/nia: Delete task API and CLI

* docs/nia: Update wording for run values

Co-authored-by: Michael Wilkerson <62034708+wilkermichael@users.noreply.github.com>

* docs/nia: require condition "catalog-services" block's regexp to be configured (#11915)

Changes:
 - Update Catalog Services Condition configuration docs to new table format
 - Rewrite `regexp` field docs to be required, no longer optional
 - Remove details about `regexp` field's original default behavior when the
 field was optional

* docs/nia: Update status API docs to table format

* Cleaner wording for response descriptions

Co-authored-by: mrspanishviking <kcardenas@hashicorp.com>

* docs/nia - 'source_includes_var' changes (#11939)

* docs/nia - condition "services" new field source_includes_var

 - Add new configuration details for condition "services" block's
 `source_includes_var` field.
 - Note: this field's description is worded differently from condition type's
 `source_includes_var` since a services variable is always required (unlike
 other vars) for CTS modules.
 - Also worded in a way to anticipate renaming to `use_as_module_input`

* docs/nia - change 'source_includes_var' default value from false to true

 - Update configs
 - Table-ify Consul-KV condition (reuse wording from Consul-KV source input)

* docs/nia - reword task execution page for source_includes_var changes

 - Note: switched to using "module input" language over "source input" language.
 Separate PR will make a mass change across docs
 - Slim down general task condition section to have fewer details on module input
 - Updated services, catalog-services, and consul-kv condition sections for
 source_includes_var
 - Add config page links for details

* Improve CTS acronym usage
- Use Consul-Terraform-Sync at the first instance with CTS in brackets - Consul-Terraform-Sync (CTS) and then CTS for all following instances on a per-page basis.
- some exceptions: left usage of the term `Consul-Terraform-Sync` in config examples and where it made sense for hyperlinking

* Improve CTS acronym usage (part 2) (#11991)

Per page:
- At first instance in text, use "Consul-Terraform-Sync (CTS)"
- Subsequent instances in text, use "CTS"

* Update schedule condition config to table format

* Update config tables with type column

* docs/nia: Update required fields values

Standardizing Required/Optional over boolean values.

* docs/nia: Standardize order of columns

Updated Required to come before Type, which is how the configurations are formatted. Also
changed the empty strings to "none" for default values.

* Deprecate port CLI option for CTS and updated example usage

* docs/nia cts multiple source input configuration updates (#12158)

* docs/nia cts multiple source input configuration updates

CTS expanded its usage of `source_input` block configurations and added
some restrictions. This change accounts for the following changes:

- `source_input` block can be configured for a task. No longer restricting to
scheduled task
- Multiple `source_input` blocks can be configured for a task. No longer
restricting to one
- Task cannot have multiple configurations defining the same variable type

Future work: We're planning to do some renaming from "source" to "module" for
v0.5. These changes are made in the code and not yet in the docs. These will be
taken care of across our docs in a separate PR. Perpetuating "source" in this
PR to reduce confusion.

The interface is documented as 'Sign will only return the leaf', and the other providers

is likely just something we missed. It doesn't break anything , but it does cause confusing cert chains
in the API response which could break something in the future.

Daniel Nephin 8a6e75ac81 rpc: add errNotFound to all Get queries
Any query that returns a list of items is not part of this commit.

Daniel Nephin 4b33bdf396 Make blockingQuery efficient with 'not found' results.
By using the query results as state.

Blocking queries are efficient when the query matches some results,
because the ModifyIndex of those results, returned as queryMeta.Mindex,
will never change unless the items themselves change.

Blocking queries for non-existent items are not efficient because the
queryMeta.Index can (and often does) change when other entities are
written.

This commit reduces the churn of these queries by using a different
comparison for "has changed". Instead of using the modified index, we
use the existence of the results. If the previous result was "not found"
and the new result is still "not found", we know we can ignore the
modified index and continue to block.

This is done by setting the minQueryIndex to the returned
queryMeta.Index, which prevents the query from returning before a state
change is observed.
