Optimize the input parameters for LeaderBalancer

[CRZbulabula]

Optimize the input parameters for LeaderBalancer to:

  public abstract Map<TConsensusGroupId, Integer> generateOptimalLeaderDistribution(
      Map<String, List<TConsensusGroupId>> databaseRegionGroupMap,
      Map<TConsensusGroupId, TRegionReplicaSet> regionReplicaSetMap,
      Map<TConsensusGroupId, Integer> regionLeaderMap,
      Map<Integer, NodeStatistics> dataNodeStatisticsMap,
      Map<TConsensusGroupId, Map<Integer, RegionStatistics>> regionStatisticsMap);

The leader balancing process thus has the ability to consider both cluster NodeStatistics and RegionStatistics
