Check_MK Werk 6551: Fixed missing permission checking during "Discard changes"

ID: 6551 Title: Fixed missing permission checking during "Discard changes" Component: WATO Level: 2 Class: Bug fix Version: 1.6.0i1 Users with reduced privileges that have access to WATO e.g. for managing their own hosts in specific folders have access to the "Activate changes" page for activating their config changes. On that page there is a button "discard changes" which can be used to undo the configuration changes that have been made since the last activation. A limitation of this feature is that it can only revert the whole configuration at all, not only the configuration made by this user. A permitted user would discard all changes, even the ones made by others in the moment he clicks on discard changes. The activation mechanism is aware of the situation where others have made changes. Users that are not permitted to activate foreign changes are not able to activate their changes in this situation and get a warning message about this. However, the discard changes action was missing such a check which allowed those users to discard the changes of others while they should not be allowed to do so. The discard changes action is now using the same logic as the activate changes action for checking whether or not a user is allowed to do this.
