This commit adds a new pair of options to the DB API function get_run_times_grouped_by_run_metadata_key() to optionally filter the results to runs with a particular key value run_metadata pair. This is useful if you want the results grouped by one run_metadata key but limited to runs with particular key value metadata pair. Change-Id: I6d499362eac158873ec982c7b6f2b91a96033a82
