This is a follow-up to 55e404e7a8, which
removed some warnings related to these fields.
These fields in the /info response were used to warn users if netfiltering
was not enabled on the host when the daemon started. Starting with
[moby@db25b0d], detecting whether netfiltering is enabled now
[happens when needed][1], making the state that's detected at startup
irrelevant.
These fields will therefore be deprecated in future, but we can start
removing their use in tests.
