Clean-up how interface address/network rules are generated.

Add modulate state as an option for state tracking

remove filter_address_add_vips_subnets and references to it, since it is no loger needed with (<if>) and (<if>:network) syntax

* added dynamic DNS support for Google Domains

* use tabs to be consistent
