There are two different concerns here. One is configuring the gitea
and gerrit services. This is independent from the management of
projects running inside them.
Make a manage-projects playbook which currently runs gitea-git-repos
but will also get a gerrit-git-repos role in a bit. Make a
service-gitea playbook for deploying gitea itself and update
run_all to take all of that into account. This should make our
future world of turning these into zuul jobs easier.
Add several missing files to the files matchers for run-gitea
and run-review.
Also - nothing about this has anything to do with puppet.
