        Generate an optimal route priority.
        参数:
        replicaSets - All RegionGroups
        regionLeaderMap - The current leader of each RegionGroup
        dataNodeLoadScoreMap - The current load score of each DataNode
        返回:
        Map, The optimal route priority for each RegionGroup. The replica with higher sorting result have higher priority.
