Ceph

Currently mkfs looks like:

- create initial states on each monitor independently
 - start them up and they'll form a quorum and go from there.

Instead, we want to

- seed each mon with the mon. key and some initial keys
 - on startup, look for an existing quorum.  if it exists, sync committed stuff and then join.
 - if quorum does not exist, try to form a new one.  
 - once a quorum is formed, if there is no initial state, create it using the seed data.

Or something along those lines. I suspect we need to take a hard look at how the election stuff currently works so that new monitors can discover each other without disrupting an existing active quorum, and form a new quorom with a subset of the live nodes. Currently the assumption is that alive => will join quorum, which isn't quite what we want.

This will enable a robust parallel mkfs/bootstrap driven by chef/whatever without any ordering requirements.
