[j-nsp] certain commands executed on CLI provide additional information over corresponding RPCs

[Saku Ytti]

Hey Phil,

I'm hijacking this for a bit.

You have | display json and xml, I assume json was relatively modest
amount of work, as you have formal source of data, so someone only
needed to write translator, without being aware of all context to
support | display json, which also means, no one needs to do any work
to get display xml or json to work on new command introduced?

If this is remotely true, shouldn't it be equally possibly to present
all data over SNMP which is presentable as JSON and XML? There are
bunch of gaps on relatively important stuff, which I'd love to see
available in SNMP. This week particularly I was frustrated to find how
'show class-of-service fabric statistics' is not available over SNMP.
Perhaps introduce some CLI-MIB where all json/xml supporting commands
are generated in OIDs and command in CLI to ask OID for particular
command?
