Title: Whether or not a relay is enabled should be configurable and not environment dependent

UIC's relays aren't working on stage because `ReservationInstrumentSwitcher#relays_enabled?` is only ever true in environment "production". Admin reservations worked, however, because `InstrumentsController#switch` enabled for all environments except test. This PR determines whether or not a relay is enabled by looking at a setting, not environment.
