Fix k8s client (#379)

* Fix k8s client to use client-go

* Fix Kubernetes Build Issue

The client-go code requires you to vendor. I have done a hack here
in the Makefile to vendor it to version 1.5. But looks like we
will need to do this the 'right' way soon.

* Convert v1 to api Objects in List Functions

Also removed the endpoint controller which was not used for anything.
The Watch functions may still need the same treatment.

* Vendor client-go release-1.5

* Fix basic SRV feature

This is actually not serving SRV records correctly, but this should
get it to work as it did prior to the k8s client changes. Another
fix will be needed to serve SRV records as defined in the spec.

* Add additional output in test result

Add the response to the test output.

* Fix erroneous test data
