      To allow the analyzeShardKey command to determine if a candidate shard key can lead to a hot chunk, we need the ability to simulate routing based on the synthetic routing table created based on the candidate shard key (SERVER-68754) and to figure out which chunk ranges each query targets. Currently, the ChunkManagerTargeter and ChunkManager only return the shard ids that each query targets. So we need to make the target methods also return chunk ranges.
