* Move k8s modules to dynamic backend * 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 * remove invalid doc refs * If fuzzy searching finds a resource, update resource_definition to match proper kind and version * remote unsupported openshift_raw variables * properly check environment variables when determining auth method:
