Donald Hunter Jan. 11, 2025, 3:48 p.m. UTC
Add a --family option to ynl to specify the spec by family name instead
of file path, with support for searching in-tree and system install
location and a --list-families option to show the available families.

./tools/net/ynl/pyynl/cli.py --family rt_addr --dump getaddr

Changes in v2, thanks Jakub:
 - Change help text for --list-families
 - Only disable schema check when installed
