[Push] Upon notification, only enqueue sync for the respective service type

[rfc2822]

Currently, UnifiedPushReceiver enqueues syncs for all authorities (contacts, calendar, tasks) and all collections of the account.

While it's more complicated to enqueue only a sync for the affected collection (because we would have to keep track of already requested ones, merge when a new sync is enqueued etc), it should be relatively easy to only sync

• contacts when the push message is for a CardDAV collection,
• calendars/tasks when the push message is for a CalDAV collection.

Is the information required already provided by the Nextcloud extension right? I mean, to know which collection has been updated.

Yes, the collection can be derived from the topic – we can look in the Collections table which collection has the topic that is sent with the push message.

I must have missed what's the intended way to use the UP feature. Now I have some script that detects changes and sends a dummy message to user topic when I need to force an update.
But now I notice that there is a "nextcloud extension" and that there's a way to request only some updates and not all. Is this documented somewhere? Thanks
