Title: additional configuration for determining internal address

Description:
Currently Envoy determines whether the address is an internal address or not based on RFC 1918. However in some of our use cases we need RFC 6598. It would also be useful to allow internal subnets to be configurable.

The feature request is to enhance Internal Address Config and add those two parameters.

Sure makes sense to me.

I think it would make the most sense to allow configuring a list of CIDRs to be considered internal, and if unset, defaults to the current behavior of RFC 1918.

Related to (or maybe a dupe of) #2590.
