tools: ynl: add YNL test framework 



Add a test framework for YAML Netlink (YNL) tools, covering both CLI and
ethtool functionality. The framework includes:

1) cli: family listing, netdev, ethtool, rt-* families, and nlctrl
   operations
2) ethtool: device info, statistics, ring/coalesce/pause parameters, and
   feature gettings

The current YNL syntax is a bit obscure, and end users may not always know
how to use it. This test framework provides usage examples and also serves
as a regression test to catch potential breakages caused by future changes.
