        Generate an optimal leader distribution.
        参数:
        regionReplicaSetMap - All RegionGroups the cluster currently have
        regionLeaderMap - The current leader of each RegionGroup
        disabledDataNodeSet - The DataNodes that currently unable to work(can't place RegionGroup-leader)
        返回:
        Map, The optimal leader distribution
