> Add support for listeners to ServerManager and AssignmentManager.
> This will allows to get notified about servers added/removed or regions added/removed/moved.
> I'm planning to use this in the MasterProcedureManager. Since we are starting using the
Procedures for distributed operations, we must add support for RS joining or Regions moving.
At the moment the operation on the "moving" set of RSs is "lost".
