UI: Individual service approvers should be configured per resource in Admin » Settings » Approvers.

[nopivnick]

this will involve refactoring some of the recent work done on #985, specifically wrt the Admin > Settings > Approvers tab UI.

the Approvers tab should have two main sections, ${permissionLabels.reviewer} and ${permissionLabels.services}.

under ${permissionLabels.services}, there should be a table for every ${resources}, sorted by roomId in increasing order.

the header row for each resource table should provide the ability to add a service approver, including:

• a dropdown menu comprised of each service available in that resource (pulled from ${tenant}-tenantSchema.resources.services)
• a text field to enter an email (that validates a NetID email with a call to the NYU Identity API)

resource table rows (service approvers) should have three columns:

• email
• service (the name of the service)
• action (a trash can icon to delete the entry)
