* update required openshift version

* update -> patch

* use new dynamic client exceptions

* style

* guard urllib3 import

* guard ansibleerror import

* give more information about error cause

* format in variable

* style

* rename tests

* Search for provided kind in a few more places to match old behavior, properly handle failure

* make common code use fail instead of fail_json, to work for lookup plugins as well

* update docs

* move openshift_raw tests into k8s tests

* fix typo

* Use diff of response and resource to determine change, don't do any checking client-side before making requests

* remove duplicate yaml blocks

* Update porting guide for k8s module
