Currently, Telemetry adds TagMap diagnostics to metrics results in order to allow users of the chromeperf dashboard to select groups of test cases (aka stories). Telemetry also adds diagnostics containing individual stories' tags.
The system would be simpler overall if the chromeperf dashboard computed tagmaps from the tags when it was collecting the test cases for the suite. This would allow removing TagMap diagnostics everywhere, at the cost of a few extra queries (1 query per test case to get its tags instead of 1 query per bot to get its tagmap).
