glusterd: Improve rebalance handling during volume sync

Glusterd will now correctly copy existing rebalance information when a
volinfo is updated during volume sync. If the existing rebalance
information was stale, then any existing rebalance process will be
termimnated. A new rebalance process will be started only if there is no
existing rebalance process. The rebalance process will not be started if
the existing rebalance session had completed, failed or been stopped.

cli : enabling/disabling quota using volume set cmd deprecated

Using the command 'gluster volume set <volname> quota {on|off}'
doesn't really enable/disable quota. So, a message to the user is
provided. Message asks the user to use 'gluster volume
quota <volname> {enable|disable}' instead.
