[full-ci] Get extended attributes for user for apps

[phil-davis]

Description

Get extended attributes for user from the apps. A
new method which emits events to get the attributes
for user, which is listened by apps to provide the
attributes for the specific user. Use case for example:
When apps are not whitelisted for guest user
they should not be visible in the personal settings.

This is a rebase of #36258

It needs someone to first decide if it is wanted, then review what it does and the technical code.

@pmaier1 is this something that is wanted? (see old PR #36258 for history/context)

[pmaier1]

If it is ready-go, yes. Otherwise I'd not spend time here at the moment.

@jvillafanez @janackermann @JammingBen can someone review this. IMO it is ready - so if it looks OK on review then it can be merged.
If you review and think it needs rework, then we can leave it for now.

Looks good to me, but we need to update all the "since" tags

@phil-davis Ooops. I cannot confirm your test results.
For me, the guest user always has access to custom groups. whitelisted or not.

Ooops. I cannot confirm your test results.

Some guest app code was never merged - see comments in owncloud/guests#516 and PR owncloud/guests#518
