Support WebSockets for Notifications / Metrics / Container Update ?

[HGGamers]

Is your feature request related to a problem? Please describe.
No, would just be a nice extra :)

Describe the solution you'd like
It would be cool to have websockets to get notifications or to be able to update containers.
Example: the Metrics Endpoint as JSON via websockets. The same could also be done for the notifications. (Btw you could also add websockets too shoutrrr).

Describe alternatives you've considered
None^^

Additional context
I'm not sure if that would be too much or even fit the project. I am sorry if someone has already requested this or it is already possible, but I have not found anything on this so far.
