What does this PR do?
As request in previous PR reviews this PR introduces
Singlemage targets for theserverlessandleakintegration test packages, similar to the existingTestKubernetesSingletarget. It adds the following functions to themagefile.go:TestServerlessSingleTestForResourceLeaksSingleInternally, both new targets delegate to shared helper functions that support selecting a specific test by name. This unifies the way we run individual integration tests across packages and prepares the mage targets for further package splits.
Why is it important?
As part of the effort to split the increasingly large integration test suite into smaller dedicated packages (see parent issue), we also need to ensure that developers can run individual tests from each new package using a consistent interface.
