rbdmirror: add retries/until when configuring mirroring

`configure_mirroring.yml` is called right after the daemon is started.
Sometimes, it can happen the first task in `configure_mirroring.yml` is
run while the daemon isn't yet ready, adding a retries/until on that
task should help to avoid causing the playbook to fail.
