Allow to retrieve the quota itself via the provisioning api

Fix #879

@AndyScherzinger special values are <0:

server/lib/public/Files/FileInfo.php

Lines 45 to 59 in e321ecd

	/**
	* @const \OCP\Files\FileInfo::SPACE_NOT_COMPUTED Return value for a not computed space value
	* @since 8.0.0
	*/
	const SPACE_NOT_COMPUTED = -1;
	/**
	* @const \OCP\Files\FileInfo::SPACE_UNKNOWN Return value for unknown space value
	* @since 8.0.0
	*/
	const SPACE_UNKNOWN = -2;
	/**
	* @const \OCP\Files\FileInfo::SPACE_UNKNOWN Return value for unlimited space
	* @since 8.0.0
	*/
	const SPACE_UNLIMITED = -3;

I guess it would be nice to backport this, and since the patch is very little, it should also be save to do so.

Nice! @nickvergessen

One small issue:

server/lib/public/Files/FileInfo.php

Line 56 in e321ecd

* @const \OCP\Files\FileInfo::SPACE_UNKNOWN Return value for unlimited space

The comment is referring to the wrong constant (c&p...) 😉

👍 for the backport since then we won't have to implement a feature detection on Android and people would just have to upgrade e.g. to 9.0.54 (or something like that). Else we would have to restrict quotas being displayed to Nc 11...

Fixed the comment.

Btw one more thing, the endpoint is from the Provisioning API App, it is shipped and enabled by default, but it can be disabled. Just to be sure that you know this and have a fallback/error handling for the missing endpoint.

[AndyScherzinger]

Uuuh, thanks for that comment 👍 Will check our code for that matter cc @tobiasKaminsky

@MorrisJobke @LukasReschke would be nice to get this one liner into 10 before the release

[AndyScherzinger]

@MorrisJobke @LukasReschke That would be awesome! 👍

[rullzer]
