      Description

      The moveChunk/mergeChunks commands do not introduce any new chunk boundaries that do not already exist. Disallowing specifying shard keys with $ in the field names that they accept prevents fixing sharding routing information, which might inadvertently have been created by older versions of the server.

      Because of this we should disable these checks.
