      Currently we implicitly create an unsharded collection on the following paths:

      1. aggregation
      2. renameCollection
      3. convertToCapped
      4. mapReduce
      5. moveChunk (on the recipient when receiving the first chunk for a collection)
      6. movePrimary (on the recipient)

      We want disallow implicit collection creation for all namespaces that are not any of:

      1. temp collections
      2. collections on the config server
      3. local/admin collections
      4. system.profile

      If a namespace does not fall into any of these categories, we should throw CannotImplicitlyCreateCollection.
