What problem would you like to solve? Please describe:
GoAlert sends alerts to various communication methods, once the alert is created it will be in unack state. there are some alerts which are in unack state forever. Any alert created in the goalert especially for monitoring productions systems should have some lifecycle and close beyond some time say 24 hrs, otherwise it won't be meaningful.

Describe the solution you'd like:
Build a configurable parameter UI to set the time threshold before the system closes the alerts which are in unack state to closed by system
In the background, all alerts which are in unack state and beyond the config time will be closed entering Closed by System, this way we can reduce the noise in the system.
