Server: CalDAV: Support calendar sharing via MacOS Calendar.app

[rumxxx]

Currently, trying to share a calendar using the MacOS Calendar.app produce the following error:

"user":"ncadmin","app":"webdav","method":"POST","url":"\/remote.php\/dav\/calendars\/ncadmin\/3F283E41-2239-452D-BE13-382E6CBB282F\/","message":"Exception: {\"Message\":\"HTTP\\/1.1 501 There was no plugin in the system that was willing to handle this POST method.\",\"Exception\":\"Sabre\\DAV\\Exception\\NotImplemented\",\"Code\":0,\"Trace\":\"#0 \\/var\\/www\\/nc12\\/3rdparty\\/sabre\\/dav\\/lib\\/DAV\\/Server.php(254): Sabre\\DAV\\Server->invokeMethod(Object(Sabre\\HTTP\\Request), Object(Sabre\\HTTP\\Response))\n#1 \\/var\\/www\\/nc12\\/apps\\/dav\\/lib\\/Server.php(253): Sabre\\DAV\\Server->exec()\n#2 \\/var\\/www\\/nc12\\/apps\\/dav\\/appinfo\\/v2\\/remote.php(33): OCA\\DAV\\Server->exec()\n#3 \\/var\\/www\\/nc12\\/remote.php(162): require_once('\\/var\\/www\\/nc12\\/a...')\n#4 {main}\",\"File\":\"\\/var\\/www\\/nc12\\/3rdparty\\/sabre\\/dav\\/lib\\/DAV\\/Server.php\",\"Line\":487,\"User\":\"ncadmin\"}","userAgent":"Mac+OS+X\/10.12.5 (16F73) CalendarAgent\/386","version":"12.0.0.29"}

SabreDAV already support this->http://sabre.io/blog/2016/sharing-changes/ and would be nice to see this implemented into NC.

I am having the same issue.

The iCal error message:

The server responded with an error.
The request for account “xxx” failed.
The server responded with“501”to operation CalDAVUpdateShareesQueuableOperation.

requires us to change from our own sharing implementation to Sabre/DAV's. Will have to evaluate how complex that's gonna be.
