Subject: [PATCH] try to alert (via webhook) when Mergify is stuck

Add a label "waiting too long" if a PR has "merge delay passed"
but is still open without any activity. Somewhat hacky, since
GitHub's API doesn't provide any real hooks for it so I'm guessing
at ways to try to catch it. Can only be tested by merging, since
Mergify won't apply it unless it's on `master`.
