Allow go-leak linter to fail CI

[yurishkuro]

Which problem is this PR solving?

• Part of Enable and enforce goroutine leak checks in tests #5006
• We have only two packages remaining without goroutine leak checks, both integration tests, which are being worked on
• Meanwhile new code / packages do not benefit from enforcement of goleak checks because the linter does not fail CI

Description of the changes

• Add the two remaining packages into exclusion list and force a failure of the CI if anything else is missing goleak checks

How was this change tested?

Successful exit:

$ make goleak
Verifying that all packages with tests have goleak in their TestMain
🔴 Error(check-goleak): no goleak check in package ./cmd/jaeger/internal/integration/
	this package is temporarily allowed and will not cause linter failure
🔴 Error(check-goleak): no goleak check in package ./plugin/storage/integration/
	this package is temporarily allowed and will not cause linter failure
🐞 Warning(check-goleak): no goleak check in 2 package(s).
	See https://github.com/jaegertracing/jaeger/pull/5010/files
	for examples of adding the checks.

Unsuccessful exit (forced by removing one of the existing checks):

$ make goleak
Verifying that all packages with tests have goleak in their TestMain
🔴 Error(check-goleak): no goleak check in package ./cmd/jaeger/internal/integration/
	this package is temporarily allowed and will not cause linter failure

🔴 Error(check-goleak): no goleak check in package ./plugin/storage/integration/

⛔ Fatal(check-goleak): no goleak check in 3 package(s), 1 of which not allowed.
	See https://github.com/jaegertracing/jaeger/pull/5010/files
