Move k8s_auth library from community.kubernetes to openshift_auth (#33)

* Add openshift_auth module

* add task to print out config

* Attempt to configure auth

* Update molecule/default/tasks/openshift_auth.yml

* fix sanity test and use incluster address for now

* Get integration tests passing locally

* Give test user cluster-level admin permissions

* Use a less verbose resource for testing

* Add alias to k8s_auth for backwards compatibility
