Add a panic button for disabling notification for a period of time

[theFeu]

Is your feature request related to a problem? Please describe.

Turning off all notifications is currently only possible in the Monitoring Health tab and this is also an on/off switch that needs to be turned back on. In the heat of a bigger outage, it would be useful to have a button somwhere that just turns off all notifications for half an hour and then automatically back on.

Describe the solution you'd like

Have a submenu under System that does just that, mute all notifications for half an hour, and turns them back on afterwards. Maybe with an "Are you sure?" modal.

Additional context

Have heard this request from customers and other Icinga / Nagios users and thought it would be worth requesting :)

In icinga1 there was the posibillity to turn off notifications of an instance "forever" (until someone re-enables it) AND to turn it off til a certain point in time. To have this posibillity again would be awesome!

I see two possibilities how this can be implemented

1. provide the api endpoint in icinga2 for disabling notifications from ...till... create a module and use the endpoint
2. create a module that can toggle notifications, schedule notifications create a scheduler that enables notifications again based on schedule
