Jakub Kicinski e4b48ed460 tools: ynl: add a completely generic client
Add a CLI sample which can take in arbitrary request
in JSON format, convert it to Netlink and do the inverse
for output.

It's meant as a development tool primarily and perhaps
for selftests which need to tickle netlink in a special way.
