WIP KUDU-2780: create thread for auto-rebalancing
The auto-rebalancer thread is a background task of the master's catalog manager.
Each loop iteration, the thread collects information on tservers, tables, and
tablets, in order to determine the best rebalancing replica moves for the
cluster.
The loop will continue, determining and executing a certain number of moves per
iteration. The number of replica moves per server, per loop iteration, is
controlled by a flag.
If the cluster has placement policy violations, the thread will schedule and
execute
replica moves to reinstate the policy. Otherwise, the thread will perform
inter-location(cross-location), then intra-location(by table, then by tserver)
rebalancing.
If the thread finds that the cluster is already balanced, the current
rebalancing
cycle completes. The thread will sleep for a time interval, controlled by a
flag.
