As a Jingle admin, I need an Admin role

[pkarman]

Roles and scopes can come from id.prx.org

some more detail from @kookster per our MVP call on 10/9:

• create in id a new scope and role and assign it to kali (plus some test users?) -enforce at the api level in the controllers -- if this scope is present on the token, allow list/index of anything in db; if not, then you only see your own account
• frontend enforcing of that we’ll figure out later
