Move the thrasher-specific methods out of CephManager

A quick check that clients refuse to mount
when daemons are laggy, and while we're at it,
that the basics of failover work. It's a trivial
test, but it's nice to have this kind of thing
so that we don't have to wait for weird thrasher
failures if something breaks.
