Commit Message

Steen Hegelund Jan. 14, 2023, 1:42 p.m. UTC 
This changes the VCAP lookups state to always be enabled so that it is
possible to add "internal" VCAP rules that must be available even though
the user has not yet enabled the VCAP chains via a TC matchall filter.

The API callback to enable and disable VCAP lookups is therefore removed.
