James E. Blair d6ae964f47 Avoid fstrings in test-prepare-workspace-git
Fstrings are not supported in python3.5 which is in use on Xenial.
We don't claim to support Xenial, but this is an easy regression
to avoid.

Also, add test jobs for this role so that we get feedback before
copying it to the prod roles.

Also, add a xenial test job to exercise it since we still have
Xenial nodes available.
