This is copied from stats/cq_status.py. If kept there, I would need to import
stats.cq_status from handlers.flake_issues, but since stats.cq_status already
also imports handlers.flake_issues, this would create a loop. I've also tried
moving it to handlers/flake_issues.py, but since it's also used in
handlers/index.py, decided to move these functions to a new file.

yeah, new file is LGTM.
