      Currently, when the supporting index for the shard key is hashed, the "mostCommonValues" metrics returned by analyzeShardKey command would contain the hashed values instead of the original values. This is because the aggregation pipeline for calculating the metrics uses the $meta key stage. SERVER-72814 will provide us with a way to looking documents from the hashed field values.
