The underlying rebalance operation in gluster is an asynchronous operation and 
returns a gluster task id. The rebalance operation once started can be stopped, 
as well as queried for status. See 
http://www.ovirt.org/Features/Detailed_Gluster_Volume_Asynchronous_Tasks_Management#REST_API.
 If we continue calling the action rebalance, need suggestions on how we can 
model the stop and status

Task id in this case is a gluster task id. Eli's change allows for external 
task monitoring, whereas here the gluster task will be treated as internal task 
similar to vdsm task albeit managed by gluster.
