[kudu-CR] [rebalancer] 'auto' mode for RF=1 tablet movements

["Alexey Serbin (Code Review)" <ge...@cloudera.org>]

Hello Will Berkeley, Tidy Bot, Mike Percy, Kudu Jenkins, Adar Dembo, 

I'd like you to reexamine a change. Please visit

to look at the new patch set (#10).

Change subject: [rebalancer] 'auto' mode for RF=1 tablet movements
......................................................................

[rebalancer] 'auto' mode for RF=1 tablet movements

Added logic to automatically determine whether the tool should
move replicas of tablets with RF=1. This is determined by examining the
version of Kudu and the replica management schema in the cluster, which
indicates whether the fix for KUDU-2443 applies. The fix applies
whenever the version is larger than 1.7.0.

This patch also contains a unit test for the newly introduced
Is343SchemeCluster() utility function.

The existing RebalanceParamTest provides coverage in case of
--move_single_replicas=auto (the default setting for the flag).
