[feature] Snooze / Timer pause

Is your feature request related to a problem? Please describe.
I really enjoy using changedetection (thank you!).

Describe the solution you'd like
It would be very useful for me to snooze a check. Sometimes you don't need an update for a while, so instead of pausing and remembering to unpause, it would be great to snooze for a time, or reactivate on a certain date.

Describe the use-case and give concrete real-world examples
I monitor a bunch of annual events, e.g. music festivals. Here, for a long time nothing changes. Then tickets become available and there's a bunch of changes again and again, until the event is over. I'd love to be able to snooze this check until the event is over and then automatically have it reactivated.

Additional context
Could either be a "snooze for X amount of time" or "snooze until date".

Hmm nice idea

Neat! I'd be happy to help on it, if that's wanted. I'm a Python dev but have minimal experience with Flask. If you point me in the right direction, I could give it a stab though.

Hmm I wouldnt bother until #2735 is in place, the scheduling will get a full make-over
