WIP KUDU-2780: create thread for auto-rebalancing
Created auto-rebalancer thread in background tasks of catalog manager.
Set up framework for auto-rebalancing loop.
Loop retrieves information on tservers, tables, and tablets for rebalancing.
The number of replica moves per loop iteration is controlled by a flag.
If there are placement policy violations, the current loop iteration will only
perform replica moves to reinstate the policy.
Otherwise, the auto-rebalancer will perform moves to do
inter-location(cross-location),
then intra-location(by table then by tserver) rebalancing.
If the cluster is balanced, the current rebalancing cycle completes, and the
thread will sleep for an interval, controlled by another flag.
