Go API run only tests that are needed for a certain change

[Flo4604]

When the parent ticket is done, we would still be running ALL tests for our go API even tho we might not need them.

For example when we add a new endpoint we don't have to run tests against our ratelimit//usagelimiter integration tests
Or against the full API suite, just the endpoints that are affect.

Same thing when changing go/pkg, we should only re-run tests against files that are affected by this change
