Improve DynamicListener's CI

[MbolotSuse]

After DynamicListener has been moved over to GHA (#45232), some adjustments will need to be made to further improve the CI. Specifically:

• In the ci, all tests running using go test should run with the -race flag. This includes any integration tests written using go.
• The linter configuration should be updated with a more strict set of rules.

DynamicListener's source code may require changes after these changes so that the CI passes. These changes are in scope for this work, and the source should be changed where necessary to get the CI to pass.
