        Get write replica-sets of sub-ranges that overlap with the input range.
        Parameters:
        range - range to check. The range can potentially overlap with multiple ranges. For example, a down node adds one failure of a token range that covers multiple primary token ranges that replicate to it.
        localDc - local DC name to filter out non-local-DC instances. The parameter is optional. When not present, i.e. null, no filtering is applied
        Returns:
        the write replicas of sub-ranges
