Samir Talwar 0ff716df2a Ledger API: Add healthcheck endpoints. (#3573) 
* grpc-definitions: Delete health_service.proto

We can use the version in io.grpc:grpc-services instead.

* ledger: Delete ledger/API.md.

* sandbox: Fix warnings in ApiServices flagged by IntelliJ.

* sandbox: Implement a dummy grpc.health.v1.Health.Check endpoint.

* sandbox: Implement a dummy grpc.health.v1.Health.Watch endpoint.

* sandbox: Drop repeated elements from grpc.health.v1.Health.Watch.

* sandbox: Wrap the HealthService in basic tests.

* sandbox: Stop streaming the server health too.

* ledger-api-test-tool: Health check tests.

* Add a changelog entry for the health check endpoints.

CHANGELOG_BEGIN

- [Ledger API] Add healthcheck endpoints, conforming to the
  `GRPC Health Checking Protocol <https://github.com/grpc/grpc/blob/master/doc/health-checking.md>`_.
  It is always ``SERVING`` for now.

- [DAML Ledger Integration Kit] Add conformance test coverage for the
  ``grpc.health.v1.Health`` service.

CHANGELOG_END

* ledger-api-integration-tests: Increment the number of services.

* Apply suggestions from code review

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

* sandbox: Use `AkkaBeforeAndAfterAll` in the HealthServiceSpec.

In an attempt to get it working on CI.

* sandbox: Change `dropRepeated` to `DropRepeated()`.

Keep it in one file.

* test-common: Use `Delayed.by` in `TimeBoundObserver`.

* test-common: Close the source when `TimeBoundObserver` completes.

* ./fmt.sh

That'll teach me not to `--no-verify` just because it's a merge commit.

* sandbox: Inline `HealthService.suppress`.

At some point it was being used twice.

* sandbox: Increase the timeout for HealthServiceSpec.

* sandbox: Reimplement HealthService using the Scala protobuf types.

* sandbox: Generate an Akka-compatible trait for the health service.

And refactor a lot of test code to make it easy to test.

* ledger-api-common: Move the HealthService here.

* rs-grpc-testing-utils: Publish to Maven.

* rs-grpc-testing-utils: Add Maven coordinates.
