slice of resolved IP addresses for the domain.

The design changed during integration and testing, resulting in the
earlier implementation growing in the appc package to be intended now
only for the sniproxy implementation. That code is moved to it's final
location, and the current App Connector code is now renamed.

An EmbeddedAppConnector is added that when configured observes DNS
responses from the PeerAPI. If a response is found matching a configured
domain, routes are advertised when necessary.
The wiring from a configuration in the netmap capmap is not yet done, so
while the connector can be enabled, no domains can yet be added.

This change refactors & moves the bulk of the app connector logic from
./cmd/sniproxy.
A future change will delete the delta in sniproxy and wire it to this type.
