fix fabric8io#3972 load should not be overloaded

also moving more of the openshift impl to be client based

CHANGELOG.md

@@ -34,6 +34,7 @@
 * Fix #4579: the implicit registration of resource and list types that happens when using the resource(class) methods has been removed. This makes the behavior of the client more predictable as that was an undocumented side-effect.  If you expect to see instances of a custom type from an untyped api call - typically KubernetesClient.load, KubernetesClient.resourceList, KubernetesClient.resource(InputStream|String), then you must either create a META-INF/services/io.fabric8.kubernetes.api.model.KubernetesResource file (see above #3923), or make calls to KubernetesDeserializer.registerCustomKind - however since KubernetesDeserializer is an internal class that mechanism is not preferred.
 * Fix #4597: remove the deprecated support for `javax.validation.constraints.NotNull` in the `crd-generator`, to mark a property as `required` it needs to be annotated with `io.fabric8.generator.annotation.Required`
 * Fix #3973: removed support for Parameterizable - that was only needed as a workaround for non-string parameters.  You should instead include those parameter values in the map passed to processLocally.
+* Fix #3973: openShiftClient.templates().load and openShiftClient.load will no longer automatically process / create templates.  Use the method openshiftClient.templates().from to get a template from any stream.
