    Description

      If I run the listIndexes command on a time-series view, normally it returns the name of the view as "ns":

      > db.runCommand({listIndexes: 'example'})
      {
              "id" : NumberLong(0),
              "ns" : "test.example",
              "firstBatch" : [
                      ...
              ]
      }
      

      But if it's a sharded time-series view, instead it replies with the name of the buckets collection:

      > db.runCommand({listIndexes: 'example'})
      {
              "id" : NumberLong(0),
              "ns" : "test.system.buckets.example",
              "firstBatch" : [
                      ...
              ]
      }
      

      I think it should return the name of the view in both cases, since the buckets collection is an implementation detail.

      Sounds like this happens because mongos translates a listIndexes request on the view, to listIndexes on the buckets collection. So it needs to also translate the response.
