[Marketplace] New permissions added to an existing RC app should update existing users permissions appropriately

[spencern]

When new permissions are added to existing permission groups (e.g. through the registry), existing users should have their permissions updated appropriately.

This could possibly be accomplished by checking and updating a permission group for authorization rather than that each user has a specific permission if the user is in a specific group.

Currently when new permissions are added to defaultRoles existing users are not granted those permissions.

@impactmass - I think this is partially completed by your groups PR as changing the permissions in the dashboard will update all users with that group, correct?

What is not completed here is if you use the addRolesToGroups method I don't think that checks existing users.

Yes. Changing it in the dashboard updates the users. The pending part is addRolesToGroups.
