[WIP] Ajax load groups in users page

[PVince81]

Fixes #9201

• The sidebar contents is now loaded with ajax.
• Use select2 for dropdowns in the users page
• Remove preloading of groups on the server side to avoid initial delay

@LukasReschke I'm not sure we want to merge this as is, it will double the load for no gain.
I'll try to put in the select2 stuff next.

[PVince81]

Needs #10968 to be merged first so I can reuse the select2 utility function. I'll work on a local rebase in the meantime...

[LukasReschke]

k - I'll review #10968 in the meanwhile.

[PVince81]

Work in progress for select2 on a separate branch: lazyloadgroups-select2 and it already seems to work fine, apart for some layout issues.
Once #10968 is merged I'll move the changes here.

Now this is an interesting and promising approach.
You will get bonus points when you can modify fetching of $filteredUsers

$filteredUsers = $this->userManager->search($search);

to also use a limit and offset to make it faster with big user bases. Load a batch of users, if the result will still be < limit take the next batch until the limit is fulfilled or no more users are retrieved.

I thought of pagination but don't want to do this as part of this PR.

This one is already tricky enough, seems the select2 layout might not fit in the users page... it wraps on multiple lines by default, might need some hacking.

I'm just hoping to not have to go back to multiselect and need to extend it.

My prior comment was meant for another PR, please ignore it.

[LukasReschke]

I rebased in hope that Jenkins will now be happy.

[PVince81]

I rebased and added further commits that introduce select2 in the users page.

This is still WIP as it's buggy and the layout doesn't look good.

[MorrisJobke]

As there is a blue ticket for this PR: @PVince81 What is the state of this?

[PVince81]

Rebased.

But still requires #20493

[PVince81]

• TODO: make select2 disappear and transform to a regular ellipsized list. Then on hover, make the select2 box appear for editing.

[PVince81]

Not a priority right now and we managed to improve perf quite a bit already -> backlog

having 200 users and 1 group, ownCloud 10.0.0beta2

users?offset=0&limit=101&gid=&pattern=	status: 200	25.1 KB	1.41 s

users?offset=0&limit=202&gid=&pattern=	status: 200	48.9 KB	2.40 s

This needs some rework using the power of new account table. For 10.0.1.

[PVince81]

old, conflicts... but still wanted... the JS code of the users page is not nice

[felixboehm]

@PVince81 development or triage?

[PVince81]

no time -> triage

[PVince81]

too many conflicts, needs to be redone
