Add UUIDResolver

The UUIDResolver adds a route at `/by-uuid/:uuid` that enables
applications to request information about a given UUID.

The UUID must be a Random UUID (version 4, see RFC 4122).

If an invalid UUID is given, the controller will return 422 Unprocessable Entity.

If a valid UUID is given:

- 404 indicates that the UUID is not assigned to anything known to the system.
- 302 indicates that the UUID was assigned to a record, and the User-Agent
  will be redirected to that record's Location as indicated in the response header.
- 200 indicates that the UUID was assigned to more than one record (which is unlikely)
  and will list those records.
