Do resync if the image is in unknow or in error
state.
Check for the current image state for up+stopped
or up+replaying and also all peer site status
should be un up+stopped to confirm that resyncing
is done and image can be promoted and used.

the rbd mirror state can be in enabled,disabled
or disabling state. If the mirroring is not disabled
yet and still in disabling state. we need to
check for it and return abort error message if
the mirroring is still getting disabled.

added ReplicationServer struct for the replication related
operation it also embed the ControllerServer which
already implements the helper functions like locking/unlocking etc.

code readability and easy maintaince.
