Discussions: close a discussion

[mrsimpson]

Motivation

Usually, a discussion is being created to discuss something with a goal. Once this goal has been achieved, the discussion is going to be deserted. Semantically, it's "done".

Proposal

The same semantic already exists for a room: "Archived". Once a room is archived, it can still be read, but subscriptions are hidden (so that the side panel is getting cleaned up) and the room is write-protected.
The "archiving" function could be re-used, it just needs to be made more prominent. A dedicated button either next to the message area or in the room properties (maybe even replacing leave/hide) would help.
In addition to that, the status "closed" should be visualized on the discussion-started-message in the parent room.

It would also be nice to have a permission to allow users to leave discussion, but not public channels or private groups!

It'd be great also to be able to turn a Discussion into a room or private group

Is this something that will be implemented?

Checking in again, wondering how I can keep a tidy left sidebar (by deleting Discussions that are no longer being discussed). This is a borderline dealbreaker for our use case if the user can't get rid of Discussions. Are Discussions designed to live forever unless an Admin goes and deletes them?

Will the left sidebar continue to fill up with new Discussions (most dead Discussions don't have a new owner to assign), and is the whole app designed to encourage users to have an endless stream of stuff, only focusing on unread at the top, and not worrying about loads of stuff filling up the bottom like dead Discussions? Thanks

Being able to "close" a discussion I think would make it a nice choice for PR review integration. Ex: A new PR starts a discussion. Within the review, you might talk about things and there might be some things that thread out, but is part of the same discussion. Ultimately, the discussion get closed when the PR gets closed.

In integrations/slack#660 the request is for PR comments to go into a slack thread. Seems like rocket chat's "discussion" would be able to provide a better workflow, assuming the discussion eventually ends.
