Automatically clear user status after a specific time

Problem to solve

Users can set their status, but there is no way to automatically clear it after a specific time.

It can be very userful, for example if you are on vacation, or in any case you already know how long your status will be valid for.

This is something you can do on Slack.

Target audience

This feature could be useful to any GitLab user.

Proposal

Improve the GitLab status to allow the described behavior.

What does success look like, and how can we measure that?

Count how many people are setting an auto-clear option for their status.
