Add a "full record" view for admins

[adrianthedev]

Feature

Sometimes I'd like to view the full record just as it is in the database without pushing an update to the resource and exposing new fields.

I'm thinking about a feature where we create the notion of an admin user for Avo and that admin user might be able to expose a "json-like" (maybe use the awesome-print gem for that) representation of that record if they want it.
