Investigate ways to DRY out lists of admin users

[sandbergja]

Currently, we maintain several lists of admin users that largely duplicate each other (for bibdata, orangelight, and lib_jobs) in princeton_ansible. These lists often include DACS and the Alma Tech Team. We should investigate ways to make sure that these don't get out of sync. One idea that seems promising is to establish an ldap group (or use the Sensu/Ansible Tower group that includes all developers) and authenticate against LDAP in the applications. The e-resources team is also using a staff group tool called Grouper, let's look into that too!
