Add button to hide jobs in list

[adswafford]

There is no way for users to clear failed (error) jobs, interrupt stalled (running for days without heartbeat or stuck in queue) jobs.

We have 2 options here: automatically hide or allow the user to hide. The former has less changes involved, what about automatically hiding all the errors, except that last 5 (or 10)?

[adswafford]

Automatically hiding failed jobs is fine to me since there isn't really much user-informative information there.

This is now possible but the hidden button is not shown in the job list. Gonna keep this issue open and rename it to make it clearer.
