Custom ContextEngineId
++++++++++++++++++++++
Send SNMP GET request using the following options:
* with SNMPv3 with user 'usr-md5-des', MD5 auth and DES privacy protocols
* use remote SNMP Engine ID 0x80004fb805636c6f75644dab22cc (USM
autodiscovery will run)
* over IPv4/UDP
* to an Agent at demo.snmplabs.com:161
* setting SNMPv2-MIB::sysName.0 to new value (type coerced from MIB)
Functionally similar to:
| $ snmpset -v3 -u usr-md5-des -l authPriv -A authkey1 -X privkey1 -E 80004fb805636c6f75644dab22cc demo.snmplabs.com SNMPv2-MIB::sysORDescr.1 = "new system name"
