Add an option to have no notifications when away or busy

I've seen option like that in other software and it's very veeery useful.

When I change my status to be away or busy, I don't want to see notifications pop up on my screen, because… hey… I'm busy. :)

Maybe it could continue to list in the notification panel, but not pop up in a banner… dunno. But at least no banner.

There are option in GS settings to disable notification popups.
The extension itself does not have control to show the banner or not. It just call notify and the rest is gnome shell.

Yeah ok.

But the core of the request is to be able to disable notif if away or busy. It's ok if no notif at all. Cause when we explicitly said we are busy, don't want to be disturb.
