  //
  // We then construct a massive OR condition and append it to any specified
  // filter condition. We also maintain an ordered array of release versions
  // to order the results returned from the metrics endpoint.
  //
  // Also note that we request a limit of 100 on the metrics endpoint, this
  // is because in a query, the limit should be applied after the results are
  // sorted based on the release version. The larger number of rows we
  // request, the more accurate our results are going to be.
  //
  // After the results are sorted, we truncate the data to the requested
  // limit. This will result in a few edge cases:
  //
  //   1. low to high sort may not show releases at the beginning of the
  //      selected period if there are more than 50 releases in the selected
  //      period.
  //
  //   2. if a recent release is not returned due to the 100 row limit
  //      imposed on the metrics query the user won't see it on the
  //      table/chart/
