Samir Talwar 5dd38d54e8 sandbox: PostgreSQL health checks. (#3655)
* ledger-api-test-tool: Increase the duration when watching health.

This should hopefully stop CI from flaking out.

* reference-v2/sandbox: Avoid unnecessary companion object constructors.

I like indirection… when it does something.

* ledger: Propagate empty health checks throughout the services.

* reference: Remove duplication from the ReferenceServer object.

* ledger-api-common: Actually query a "reporter" in the health service.

* ledger-api-common: Report health per-component when required.

* ledger-api-health: Use a Map to represent components for health checks.

* sandbox: Fix warnings in SqlLedgerSpec.

* ledger-api-common: Throw GrpcHealthService errors inside the Future.

* ledger: Implement health checks against the PostgreSQL connection.

Without proper testing, because I am not great at this.

* sandbox: Remove duplication and fix warnings in PostgresAround.

* sandbox: Test the SQL Ledger's health reporting on failure.

* sandbox: Don't report as unhealthy until 3 connections fail.

* ledger-api-health: Remove unused parts of the API.

Bit of premature design there.

* sandbox: Rename the "ledger" health check to "write".

* participant-state: Add the ReportsHealth trait to ReadService.

* ledger-api-common: `Future.fromTry(Try(…))` -> `Future(…)`.

* ledger-api-common: Make it clearer that StubReporter closes over health.

* ledger-api-common: Explain the HealthService watch tests with comments.

* sandbox: Clean up SqlLedger a bit.

* sandbox: Don't try and stop PostgreSQL twice in PostgresAround.

* bazel_tools: Windows rlocation lookups need to be with forward slashes.

* release: Fix case of "true".

* ledger-api-common: Make `GrpcHealthService::matchResponse` return a Try.

* ledger-api-common: Make `GrpcHealthServiceSpec` async.

* sandbox: Make a couple of DB classes final.

* sandbox: Avoid importing `X._` in PostgresAround.

* sandbox: Add clues to the SqlLedgerSpec's multiple assertions.

* sandbox: If PostgreSQL doesn't come back up, keep retrying.

* sandbox: Remove duplication in SqlLedgerSpec.

* sandbox: In SqlLedgerSpec, actually wait for the health to change.

* sandbox: In PostgresAround, make stopping PostgreSQL idempotent.

* sandbox: Simplify the SqlLedgerSpec to make it work on CI.

It's worth a shot.

* ledger-api-common: Simplify the GrpcHealthServiceSpec a little.

And add a changelog.

CHANGELOG_BEGIN

- [Ledger API Server] Add a health check endpoint conforming to the
  `GRPC Health Checking Protocol <https://github.com/grpc/grpc/blob/master/doc/health-checking.md>`_.
- [Ledger API Server] Add health checks for index database connectivity.
- [Participant State API] Add a mandatory ``currentHealth()`` method to
  ``IndexService``, ``ReadService`` and ``WriteService``.

CHANGELOG_END

* sandbox: Improve the Javadoc layout for DbDispatcher.

* sandbox: Capitalize constants in SqlExecutor.
