A recent regression showed up in the tempest tests, but as they were not

time to be wasted debugging.
We should make more of the jobs voting and fix any instability (or
remove particular tests that are unstable).

Zuul now supports including the file extension on the playbook path
and omitting the extension is now deprecrated. Update references
to include the extension.
