[AGENT++] [SNMP++]Finding V3 enabled Device

I just tried with the current version. If the agent does not answer (as
it should if it does not speak v3), it is not reported as discovered.
Can you check with tcpdump/wireshark, what the device sends back?
On the other side, the broadcast_discovery() function does not check
anything on the received packet. So even if some device answers with a
DNS response, it is added to the address collection.

If you want to be sure, that the device can speak v3, you have to use
the engine_id_discovery() function and check if you can get a engine id
with v3MP::get_from_engine_id_table().

But be aware, that there is no requirement for an agent to answer
requests sent to a broadcast address.
