示例1: listCollection
// listCollection will list the items in the specified namespace
// it returns the following:
// the list of items in the collection (if found)
// a boolean if the operation is supported
// an error if the operation is supported but could not be completed.

dynamicClient *dynamic.Client,
opCache operationNotSupportedCache,
gvr unversioned.GroupVersionResource,
namespace string,

// this is strange, but we need to special case for both MethodNotSupported and NotFound errors
// TODO: https://github.com/kubernetes/kubernetes/issues/22413
// we have a resource returned in the discovery API that supports no top-level verbs:
// /apis/extensions/v1beta1/namespaces/default/replicationcontrollers
// when working with this resource type, we will get a literal not found error rather than expected method not supported
// remember next time that this resource does not support delete collection...
