websocket instead of push notifications (firebase for android)

Hello, I've read this jami post, as well as others, including bugs, about the jami proxy, which is set by default on android accounts.

I don't understand why going all the way to provide a firebase push notification mechanism for android (and equivalent for apple), if a websocket mechanism could have been used, like the molly-foss one.

Could you please consider an alternative jami proxy providing websocket service, rather than hooking with firebase, as an alternative?

I know for now, if not wanting to hook to firebase, the alternative is to disable jami proxy, and make sure running in the background is enabled, but that consumes more battery than websockets which is a better alternative than firebase, though it still requires running in the background...

This of course is, in my mind, an enhancement to current functionality available...
