add an action to add labels to issues closed by MRs
ParaView's workflow uses a state between "fix merged" and "issue closed" where customers are expected to verify the issues are actually fixed. To accomodate this, issues should be given labels upon merging of an MR (possibly controlled by labels on the MR itself) and opened, assigned to the relevant customer(s).
The model is that issues belong to boards (milestones), lists (priority and workflow labels), labels (triage labels), assignment sync (maybe). It should be two-way.
