src: add list ruleset command
This patch adds a new command to nft:
% nft list ruleset [family]
Which list the entire ruleset.
If no family is specified, all tables of all families are listed.
Users can now make several operations at ruleset level:
% nft list ruleset > ruleset.nft
% nft -f ruleset.nft
% nft flush ruleset
