* This is a job-like class to check that the server is up and that we are connected.
* There is two entry point: checkServerAndAuth and checkAuthentication
* checkAutentication is the quick version that only do the propfind
* while checkServerAndAuth is doing the 3 calls.
*
* We cannot use the capabilites call to test the login and the password because of
* https://github.com/owncloud/core/issues/12930
*
* Here follows the state machine
*---> checkServerAndAuth (check status.php)
Will asynchronously check for system proxy (if using system proxy)
And then invoke slotCheckServerAndAuth
CheckServerJob
|
+-> slotNoStatusFound --> X
|

credential->fetch() --+

+-----------------------------------+

PropfindJob
