quota API design flaw - unlimited and >1TB can't be detected

[AndyScherzinger]

Steps to reproduce

1. set a quota for to 2TB
2. call /ocs/v1.php/cloud/users/<user>
3. --> <free>1103360991232</free><used>118102553</used><total>1103479093785</total>
4. set quota for to 1GB
5. set a quota for to unlimited
6. call /ocs/v1.php/cloud/users/<user>
7. --> <free>1103360991232</free><used>118102553</used><total>1103479093785</total>
8. set quota for to unlimited
9. call /ocs/v1.php/cloud/users/<user2>
10. --> <free>1103356682240</free><used>714783</used><total>1103357397023</total>

Expected behaviour

1. if I set the quota for a user to 2TB I want this information, right now the quota is always ~1TB, e.g. for 1TB, 2TB, unlimited.
2. if the quota is set to unlimited I want to get this information so I can detect if the quota for a user is set.
3. if the quota for all existing users has been set to unlimited I want this information on all users being available (not the ~1TB info again...)

We try to use this for nextcloud/android#204 and obviously want to hide the quota display when none is set, which isn't working because of the described API behavior above.

Actual behavior

1TB, 2TB, Unlimited always set ~1TB in the quota tags...

Well quota is a number as well, but it seems to be missing from this endpoint, maybe we can add it as well.

[AndyScherzinger]

@nickvergessen atm it is the parent tag

<quota>
  <free>1103360991232</free>
  <used>118102553</used>
  <total>1103479093785</total>
</quota>

Yeah, but inside this quota, the following values could exist:

server/lib/private/legacy/helper.php

Lines 626 to 634 in 0215b00

	return [
	'free' => $free,
	'used' => $used,
	'quota' => $quota,
	'total' => $total,
	'relative' => $relative,
	'owner' => $ownerId,
	'ownerDisplayName' => $ownerDisplayName,
	];
