Add new plugin: external - resolve k8s ingress and LB address with external names (#2379)
* Add new plugin: external
This plugin works in conjunction with the kubernetes plugin and exports
ingress and LB addresses as DNS records. It bypasses backend.go and
backend_lookup.go flow because it is not needed.
README, tests are implemented. The tests only exercise the unit tests,
this has not been tested in any ci.
