Add tsdb-cat for IP SLA on C8000v

[mzagozen]

I added a secondary NSO - nso-config to push interface and IP SLA configuration via the CLI NED. In this way the schema loaded in the primary NSO remains minimal - just the new oper data models for IP SLA.

1. make start
2. make configure
3. make nso-test
