cephadm: bootstrap is not idempotent
It would be helpful if this command did nothing if the cluster is already bootstrapped. This would simplify ansible rules for deployment.

Making cephadm bootstrap truly idempotent will not be trivial. As there are going to be some special cases, like: what about existing daemons that were not created by `cephadm bootstrap`
Please don't use --allow-overwrite:
cephadm bootstrap --allow-overwrite #WRONG!
which makes you able to call bootstrap multiple times, but does not remove the old cluster.
