@enj not sure who owns prometheus, but it's not devex (we do have build metrics in prometheus but that's not what this test is).

@smarterclayton and @mfojtik show up in the git blame on the test file.

[smarterclayton]

This means that the build and the prometheus tests ran in parallel at the same time.

@gabemontero @smarterclayton so it sounds like both tests need to be updated to tolerate the existence of the service account/prometheus installation. (Unless the build test already does).
