Create a dedicated revert permission to only allow specific groups to revert changes. Groups that don't have the "Revert" permission will not see the Revert button and will not be allowed to revert changes from the GUI. This change is created due to spammers that easily use the "Revert Submission" button to create many changes quickly. Change-Id: If5180bc982659ab5c9ddaa096ac455823484c50c
