Ceph » devops

The current state of ceph-deploy for remote connections is terrible to work with. While attempting to work on #6486 that would allow to restart monitors it was
very clear that having 3 different ways to connect and execute remote functionality is gotten out of hand.

Currently, ceph-deploy has these connections types:

• with pushy, but using the old connection objects, no (or limited) logging, `compile()` called every where
• with pushy, using the modified connection objects with good logging, possibility of remote hangs, and abuse of `conn.modules.some.module.call.here`
• with remoto, using the above but in simplified ways, which is what we would end up doing

If the first 2 items do not get cleaned up, it makes very difficult and time consuming to try and add new features.
