SNMPv2c TRAP via Twisted inline callbacks
+++++++++++++++++++++++++++++++++++++++++
Send SNMPv2c TRAP through unified SNMPv3 message processing framework
using the following options:
* SNMPv2c
* with community name 'public'
* over IPv4/UDP
* send TRAP notification
* with Generic Trap #1 (warmStart) and Specific Trap 0
* include managed object information '1.3.6.1.2.1.1.1.0' = 'my system'
Functionally similar to:
| $ snmptrap -v2c -c public demo.snmplabs.com 12345 1.3.6.1.6.3.1.1.5.2 1.3.6.1.2.1.1.1.0 s "Hello from Twisted"
