Introduce UnifiedPush support in f-droid versions of android apps

[resoli]

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

F-droid versions of the official Nextcloud Android apps does not support push notifications; this is really inconvenient in particular for Talk

Describe the solution you'd like

UnifiedPush is emerging as a very nice solution, and there is server side support in Nextcloud itself thru UnifiedPush Provider app in the appstore

Additional context

UnifiedPush support is already provided in F-Droid versions of Element (matrix client) and Tusky (mastodon client) and they work very well in combination with NextPush distributor / UnifiedPush Provider

For the notifications of the various nextcloud services there is already a solution: https://github.com/Andrewerr/NextcloudServices but I agree that it would not be a bad idea to add support to unifiedpush.org considering that nextpush works very well and if already used it would avoid the need to install an additional app

[resoli]

Yes, given that NextcloudServices does not really push notifications, but a polling ...
