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.
