[j-nsp] Publish API data over SNMP

As a user I'd be comfortable at stability which matches display
XML/JSON stability, and I think that level of stability would be
implied.

All this relies on my assumption that JNPR is machine generating
JSON/XML stuff automatically for new commands, and 100% coverage is
guaranteed. If this is true, same way this CLI-MIB could be machine
generated.

In practice I rarely use MIBs, and if CLI would offer 'show
class-of-service fabric statistic | display oid', that would be good
enough for me. So not even having MIB wouldn't bother me. My only use
case for MIBs is when I try to find what OID to poll, actual tooling
does not load MIBs.

I'm not sure I understand the problem or question.
