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. Signed-off-by: Miek Gieben <miek@miek.nl> * Rename to k8s_external Signed-off-by: Miek Gieben <miek@miek.nl> * go gen Signed-off-by: Miek Gieben <miek@miek.nl>
