HBASE-23932 Minor improvements to Region Normalizer (#1258)
- consolidate checks made by master on behalf of balancer and
normalizer: deciding if the master is in a healthy state for
running any actions at all (skipRegionManagementAction). Normalizer
now does as balancer did previously.
- both balancer and normalizer make one final check on above
conditions between calculating an action plan and executing the
plan. should make the process more responsive to shutdown
requests.
- change normalizer to only consider acting on a region when it is in
the OPEN state. previously we would normalizer attempt to merge a
region that was already in a MERGING_NEW,MERGING,MERGED state.
- fix some typos in variable names.
