Decisions decisions: Add decision-making flow for stale threads (#271)

contributes to THESIS-58

### Notes
This adds a decision making process to threads with call-to-action
buttons running different interactions such as tagging a user. Will
archive a channel after 24 hours of inactivity or if the user decides to
archive.
