Simplify our Normalizer story to have just a single, configurable implementation. * fold the features of `MergeNormalizer` into `SimpleRegionNormalizer`, removing the intermediate abstract class. * configuration keys for merge-only features now share a common structure. * add configuration to selectively disable normalizer split/merge operations. * `RegionNormalizer` now extends `Configurable` instead of creating a new instance of `HBaseConfiguration` or snooping one off of other fields. * avoid the extra RPCs by using `MasterServices` instead of `MasterRpcServices`. * boost test coverage of all the various flags and feature combinations.
