Previously we set strategy: free and max_fail_percentage: 1 and this
probably made sense when we were using native ansible to do all of the
work to create projects. That was slow and broken down into many tasks.
Now however, we have a single task that calls out to a python module
that does all the work for each gitea host. That means we won't get any
additional parallelization from the free strategy. We also don't want to
stop the python module on all hosts if any of them fail, instead let
them all run to completion if they can. Then if any giteas fail we
should skip the play on review.
