As a user, I want to control how long my data is stored.

[lm-sec]

Right now, we accumulate irrelevant data at an impressive rate and we could take a chill pill and keep the data up to when it becomes irrelevant, then clean it up.

AC:

• Decide how long I want my past job run to be stored (ex: 1 or 2 weeks max, then delete)
• Decide how long I want to keep my findings
• Decide how long I want to keep a subscription trigger? Maybe just clean up triggers that are ready to fire or that don't have a subscription every once in a while?

Bonus, but not mandatory:
Admin interface to setup these values.
