snmp inspector: need to support more snmp v3 user secrity model configuration

[Lianhao Lu]

Currently, the snmp inspecotr in hardware pollsters only support authentication method of snmp v1, v2c, and part of snmp v3.

For snmp user secirty model(USM), we only support authentication prototocl of MD5 and encryption protocol of "no encryption". We need to support sha authentication and des/aes encryption, because sometimes the snmpd server is configured so.
