Add global superusers for support staff
The members of USDC and perhaps other support & admin personnel should be able to perform jobsub functions as if they were superusers in every group. Adding admins to each groups' superusers list is not a great option, as it makes for an untidy and error-prone configuration. Likely this would involve a "global" superusers list.
See also #13515 for allowing superusers access to sandboxes.
