ceph-volume: run tests without waiting on ceph repos

This provides a new playbook that installs ceph on all nodes and
generates the ceph config. Then it will rsync ceph-volume from the
control node, or jenkins slave, to all testing vms before completing
the deployment. This means we can run tests on PRs without waiting
for repos to be built for the branch in the PR.
