SNMP Server Component

[ChadSikorra]

This library should have some sort of general SNMP server component for replying to SNMP client requests. There is already a Trap Sink component capable of handling incoming client requests. Some prerequisite work is need:

• [ ] MIB support based on SMIv1/SMIv2 (separate library)
• [ ] Some sort or persistence in general for MIBs
• [ ] Additional logic in the UserSecurityModel to handle client discovery / time synchronization.
• [ ] Possible ServerListener API for programmatically handling requests

Related work in progress in the ASN.1 library, needed for MIB support: https://github.com/FreeDSx/ASN1/issues/3

I have started work on MIB parsing, though it will take a bit before I have something usable. Since it's basically implementing a subset of X.680.
