Support notifications

[oxismailxo]

Hello @eeshugerman

do you think that we can add notifications (email, webhook, slack...) to the project in case the backup fails, etc..? just an idea

Sorry but probably not given the added support burden and open-endedness (which protocols/services to support). Still, it's not entirely out of the question, so I'll leave this open.

ntfy support is super simple to implement via their web POST hook (config is host,port), and then other external clients could be listening to those notifications to trigger emails etc. This would keep the maintenance down on this project, and still allow an external message to be sent. And since ntfy can be run easily in a another container, this makes running that simple as well.
