modules_k/presence_xml Xcap auth reason when user deleted from list
The reason in Subscription-Status header in Notify when a user is deleted from the contact list can be decided by the admin by setting presence_xml module parameter xcapauth_usedel_reason. Default value is "probation". (cherry picked from commit 3abf967f61a1bd95c28d4e8a929a8bd5df00671d)
