Cleanup iptables bug TODOs

There are many references to unimplemented iptables features that link to #170,
but that bug is about Istio support specifically. Istio is supported, so the
references should change.

Some TODOs are addressed, some removed because they are not features requested
by users, and some are left as implementation notes.

Fixes #170.
