Re: ceph-deploy issues with initial mons that aren't up

"mon initial members" is a race prevention mechanism whose purpose is
to prevent your monitors from forming separate quorums when they're
brought up by automated software provisioning systems (by not allowing
monitors to form a quorum unless everybody in the list is a member).
If you want to add other monitors at a later time you can do so by
specifying them elsewhere (including in mon hosts or whatever, so
other daemons will attempt to contact them.)
