Change subject: KUDU-3760 expose follower-move flag in rebalancer ...................................................................... KUDU-3760 expose follower-move flag in rebalancer The follower-move preference added for the auto-rebalancer changed the default of TwoDimensionalGreedyAlgo's constructor to prefer follower moves. The CLI rebalance tool default-constructs that algorithm, so it started preferring follower moves silently, with no way to turn it off. Add a --rebalancing_prefer_follower_replica_moves flag (default true, to match both the auto-rebalancer's flag and the new constructor default) and plumb it through to the algorithm. This keeps the current behavior but makes it explicit and overridable from the command line. Adds a parameterized test that runs the tool with the flag set both ways and checks the cluster still ends up balanced.
