Description

The rebalancing operation may take a long time (hours, days) thus when issued from the ambari UI the background operation may time out.

As it's not possible to dynamically predict how long the rebalancing will last , the approach taken by this solution is to only trigger the operation and not wait for the operation to finish.

(Worths mentioning here, that after this change the progress of the rebalance operation won't be tracked anymore in the background operation; also the user won't be notified about the success/failure of the operation)
