End-to-end (e2e) encryption support

This would require major architectural changes for the Mattermost server, but adding some use cases to gather feedback from the community.

Server admins wouldn't be able to read the content of conversations because they don't hold the keys to decrypt, which means users wouldn't have to worry about
- Server admins spying on their private conversations
- Governments subpoening server admins into handing over conversations
- Hackers taking control of the server being able to read the conversations

    This feature would be a game-changer for a whole range of organizations working on sensitive issues (democracy groups, human rights defenders, election monitoring, international organizations, etc). For these organizations, it is paramount that ***nobody*** can read conversations except for the conversation participants, not even server admins.

    Currently, the options for an end-to-end encrypted alternative to Slack are WickrPro (very expensive and not particularly usable) and Wire (decent but nowhere near Slack). Which is why many groups are stuck on Signal, which is incredibly inconvenient for actual work communication.

    Clearly, this would be a major change to the Mattermost infrastructure, and require a large amount of work. In particular, all the cool features (reply, tag, search, etc) would be hard to implement. But it's doable (Wire has done it).
