tools: ynl: add --list-ops and --list-msgs to CLI
I often forget the exact naming of ops and have to look at the spec to find it. Add support for listing the operations: $ ./cli.py --spec .../netdev.yaml --list-ops dev-get [ do, dump ] page-pool-get [ do, dump ] page-pool-stats-get [ do, dump ] queue-get [ do, dump ] napi-get [ do, dump ] qstats-get [ dump ] For completeness also support listing all ops (including notifications: # ./cli.py --spec .../netdev.yaml --list-msgs dev-get [ dump, do ] dev-add-ntf [ notify ] dev-del-ntf [ notify ] dev-change-ntf [ notify ] page-pool-get [ dump, do ] page-pool-add-ntf [ notify ] page-pool-del-ntf [ notify ] page-pool-change-ntf [ notify ] page-pool-stats-get [ dump, do ] queue-get [ dump, do ] napi-get [ dump, do ] qstats-get [ dump ] Use double space after the name for slightly easier to read output.
