Upgrade rules-scala and scalatest (#8187)
This is necessary to at least attempt an upgrade to 2.13 and
generally, I want to keep our rulesets up2date. rules-scala forces the
version of scalatest so we have to bump that at the same time.

This requires changes to basically all Scala test suites since the
import structure has changed and a bunch of things (primarily
scalacheck support) got split out.

Apologies for the giant PR, I don’t see a way to keep it smaller.

resources: Customizable contexts. (#7678)
* resources: Move builders into //ledger/ledger-resources.

Keep the actual constructors in a trait, but instantiate it when working
with ledger code.

This allows us to later introduce an extra "context" type parameter to
ResourceOwner.

* resources-akka: Move the builders in to //ledger/ledger-resources.

* resources: Introduce an abstract `Context` parameter for owners.

This replaces the concrete `ExecutionContext`. While it _can_ be an
execution context, it really doesn't matter as long as we can get at one
somehow.

This is being introduced so we can wrap the context in a container,
either for type tagging or to include extra information.

Because our current context _is_ `ExecutionContext`, and an implicit is
provided to extract it, we can end up with two ways to get the same
value. We use shadowing to prevent this. This problem should go away in
the near future when a new context type is added.

CHANGELOG_BEGIN
- [Integration Kit] The `ResourceOwner` type is now parameterized by a
  `Context`, which is filled in by the corresponding `Context` class in
  the _ledger-resources_ dependency. This allows us to pass extra
  information through resource acquisition.
CHANGELOG_END

* ledger-resources: Move `ResourceOwner` here from `resources`.

* ledger-resources: Remove dependencies from outside //ledger.

* ledger-resource: Wrap the acquisition execution context in `Context`.

So we can add a logging context to it.

* resources: Pass the Context, not the ExecutionContext, to Resource.

* Avoid importing `HasExecutionContext`.

* ledger-resources: Publish to Maven Central.

* resources: Make the small changes suggested by @stefanobaghino-da.

Co-Authored-By: Stefano Baghino <43749967+stefanobaghino-da@users.noreply.github.com>

* ledger-resources: Pull out a trait for test resource contexts.

Saves a few lines of code.

* Restore some imports that were accidentally wildcarded.

* resources: Replace an `implicit def` with a couple of imports.

* participant-integration-api: Simplify the JdbcLedgerDaoBackend tests.

Try and use the right execution context where possible.

kutils: Make the validation and the preloading of PackageCommitter parametric (#7460)
This PR creates 3 validation modes:
* `Strict`: Specifies that the committer should validate the package
  before committing them to the ledger. When using this mode, the
  packages committed to the ledger can be fully trusted and do not
  have to be validated when loaded into the engine.
* `Lenient`: Specifies that the committer should perform a fast
  validation of the packages before committing them to the ledger.
  This mode is useful for ledger integrations that cannot handle
  long-running submissions (> 10s). When using this mode, the
  packages committed to the ledger cannot be trusted and must be
  validated every time they are loaded into the engine.
* `No`: Specifies that the committer should not perform any
  validation the packages before committing them to the ledger. This
  should be used only by non distributed ledgers, like DAML-on-SQL,
  where the validation done in the API server can be trusted.

This PR creates 3 preloading modes:
* `Synchronous` : Specifies that the packages should be preloading
  into the engine before committed.
* `Asynchronous`: Specifies that the packages should be preloaded into
  the engine asynchronously with the rest of the commit process. This
  mode is useful for ledger integrations that cannot handle
  long-running submissions (> 10s). Failure of the preloading process
  will not affect the commit.
* `No`: Specifies that the packages should not be preloaded into
  the engine.

CHANGELOG_BEGIN
-   [Integration Kit] In kvutils, add metric
    daml.kvutils.committer.package_upload.validate_timer to track
    package validation time.

Fixes #6837

Spreads usage of LoggingContext and ContextualizedLogger throughout the participant server.

Allow running StandaloneApiServer in read-only mode. (#6721)
Also fixes #5635, removing usage of `ReadService` from the `StandaloneApiServer`.

The configuration stream of the Ledger API LedgerConfigurationService is now properly backed by the configuration entries instead of just serving the initial configuration.

CHANGELOG_BEGIN
[DAML Integration Kit]: ``StandaloneApiServer`` can now be run in a read-only mode.
  - The type of the constructor parameter ``writeService`` of ``StandaloneApiServer`` changed to ``Option[WriteService]``. Passing ``None`` will not start any of the admin services, the command service, and the command submission service.
  - The constructor parameter ``readService`` of ``StandaloneApiServer`` has been removed.
  - A new constructor parameter ``ledgerId`` has been added to ``StandaloneApiServer``. It is used to verify that that ``StandaloneApiServer`` is run against an index storage for the same ledgerId. Initialization is aborted if this is not the case.
[DAML Integration Kit]: The ``LedgerConfigurationService`` now properly streams configuration changes.

Reset service improvements for sadbonx (#5728)
- Only upload packages during the initial startup.
- Avoid loading packages during subsequent resets
- Share an engine between Ledger API Server and Committer

* Use a randomized H2 URL to simular in-memory

The reset service test assumes to get a completely new ledger for each
test case. But because we use H2 in-memory with db_close_delay=1 and the
same H2 database name, the second test case gets the remnants of the
first test case.

Since we know that sandbox in-memory uses an H2 in-memory URL, we can
simply use SandboxBackend.H2Database for ResetServiceInMemoryIT.

Remove heartbeats in participant server and kvutils (#5315)

This commit modifies the java migration V2_1__Rebuild_Acs. This is safe to do, because:

kvutils: Don't supply execution contexts to ResourceOwners. (#5010)
* kvutils: Remove the unnecessary execution context from the test base.

* kvutils: Remove the unnecessary execution context from the writer.

* ledger-on-sql: Make a proper owner so it has a proper execution context.

This means the parallelization now needs to come from the test, so I've
augmented ParticipantStateIntegrationSpecBase to take a proper execution
context instead of the serial one that ScalaTest provides, with a
default of `ExecutionContext.global`.

* ledger-on-memory: Make a proper owner with a proper execution context.

* kvutils/app: Remove `executionContext` from LedgerFactory.

Shouldn't need it in `ResourceOwner`. I was bad.

CHANGELOG_BEGIN
CHANGELOG_END

* ledger-on-memory: Make ResourceOwners real classes.

* ledger-on-sql: Make the ResourceOwner a real class.

* ledger-on-sql: Cause side effects on resource acquisition.

Not on owner construction.

sandbox: Normalize language around listing all known parties. (#4895)
This renames methods backing the `ListKnownParties` request to
from `parties`, `getParties` or `listParties` to `listKnownParties`.

CHANGELOG_BEGIN
- [Ledger API Server] Renamed two metrics:
  ``daml.index.parties`` was renamed to ``daml.index.list_known_parties``
  ``daml.index.db.get_parties`` was renamed to ``daml.index.db.list_known_parties``

Sandbox: Re-use actor systems between the StandaloneApiServer and StandaloneIndexerServer. (#4827)
* sandbox: Re-use the root actor system in the StandaloneIndexerServer.

* kvutils/app: Don't use the ActorSystem execution context randomly.

Instead, make `Runner` a proper ResourceOwner, with an `acquire` method.

* sandbox: Re-use the root actor system in the StandaloneApiServer.

* resources: Remove the now-unused `ResourceOwner.sequence` functions.

They weren't well-thought-out anyway; they acquire resources
sequentially, rather than in parallel.

Remove InMemoryKVParticipantState (#4674)
This removes the sample/reference implementation of kvutils
InMemoryKVParticipantState.
This used to be the only implementation of kvutils, but now with the
simplified kvutils api we have ledger-on-memory and ledger-on-sql.

InMemoryKVParticipantState was also used for the ledger dump utility,
which now uses ledger-on-memory.

* Runner now supports a multi participant configuration
This change removes the "extra participants" config and goes for consistent
participant setup with --participant.

* Run all conformance tests in the repository in verbose mode.

This means we'll print stack traces on error, which should make it
easier to figure out what's going on with flaky tests on CI.

This doesn't change the default for other users of the
ledger-api-test-tool; we just add the flag for:

  - ledger-api-test-tool-on-canton
  - ledger-on-memory
  - ledger-on-sql
  - sandbox




Fixes #4225.

recovering-indexer-integration-tests: Extract from reference-v2. (#4636)
This moves IndexerIT into its own package, and swaps the dependency from
reference-v2 to ledger-on-memory.

This test should ideally live in the sandbox code, but because it
depends on ledger-on-memory, it's easier to keep it separate.

Also rewrites a lot of the code because the API is different. The tests
should now be clearer too.

I've also marked the test as flaky, because, well, it is.
