Timothy Andrew 3d5729a700 Add the "Production" cycle analytics section.
1. Rewrite the `Queries` module to work off a `data_point` hash, with
   `issue` and `merge_request` as keys. The "production" query needs
   both an issue and a merge request to make it's calculation, so it
   makes sense to keep things consistent and provide the same
   data (issue + merge request) for all queries.
