Barracuda Web Security Gateway support-v2

I had previously opened an issue for this, which was properly closed, since the Barracuda WSG did not return the desired values for Barracuda's OIDs during the snmpwalk.

I chased this down further with Barracuda, to determine if their MIB was out of date or if the appliance was misbehaving\reporting improperly\incompletely.

During troubleshooting with Barracuda Support, we found that if you poll the relevant OIDs directly\specifically with snmpwalk, the unit does return values.

I'd like to re-open this request to see if I can get better support for this unit in Observium – it seems like the values are available but Observium will need to poll them directly.

I will attach various snmpwalks to demonstrate the behavior.
