Allow gitea_create_repos always_update to be list

Setting the gitea_always_update var for the gitea-git-repos role to
a list will filter metadata updates to only the project names
included in the supplied list. False and True still have their prior
meanings of do no metadata updates or force metadata updates for
every project we host.

Add testing for this, and also actually test that the rename
playbook renamed something.

Get rid of the git clone in the playbook since it's no longer
relevant to how we run things anyway, we'll instead want to rely on
the Zuul supplied projects.yaml path.
