[ci-visibility] Add get known tests request

[juan-fernandez]

What does this PR do?

Add get known tests logic.

It's the first piece of the "Early flake detection" feature:

• we detect what tests are new in your feature branch
• we run them multiple times to check if they're flaky to stop you from merging flaky tests to the default branch

This PR just adds the necessary logic to request the known tests for a given test service (so the test framework can be aware of what tests are new).

Motivation

The early flake detection changes are considerable, so I'm splitting the changes in different PRs so it's easier to review.

This PR:

• Adds getKnownTests request.
• Adds getKnownTests to the ci visibility exporter, so plugins can request known tests.
• Adds corresponding tests.

This PR does not include usage of the known tests by any test framework.

Plugin Checklist

• Unit tests.

Security

Datadog employees:

• If this PR touches code that signs or publishes builds or packages, or handles credentials of any kind, I've requested a review from @DataDog/security-design-and-guidance.
• This PR doesn't touch any of that.

Not blocking, but it's a bit difficult to know why this is needed without any publisher. Generally speaking it's a pattern that should be avoided, so just pointing it out to make sure other options were evaluated.

[juan-fernandez]

that's a good point. The changes are considerable so I split the PRs, leaving this is as a noop, which isn't great. The usage will become clear very soon though, as I have the changes ready :)
