Raise an exception if a label doesn't exist
Lately, some labels were renamed and rules weren't behaving as expected because of that, e.g. gitlab-org/quality/triage-ops!51 (diffs).
I think gitlab-triage
could check for the existence of all the labels used in conditions and/or in actions, and raise an exception if any label doesn't exist because it could lead to unexpected/wrong comments.
