// Verifies that schemas that are not in the master tree of Kubernetes can be retrieved via Get.
// Because api.List is part of the Kube API, resource.Builder has to perform a conversion on
// api.Scheme, which may not have access to all objects, and not all objects are at the same
// internal versioning scheme. This test verifies that two isolated schemes (Test, and api.Scheme)
// can be conjoined into a single output object.
//
// The expected behavior of the `kubectl get` command is:
// 1. objects using unrecognized schemes will always be returned using that scheme/version, "unlikelyversion" in this test;
// 2. if the specified output-version is a recognized, valid Scheme, then the list should use that scheme, and otherwise it will default to the client version, testapi.Default.GroupVersion().String() in this test;
// 3a. if the specified output-version is a recognized, valid Scheme, in which the requested object (replicationcontroller) can be represented, then the object should be returned using that version;
// 3b. otherwise if the specified output-version is unrecognized, but the requested object (replicationcontroller) is recognized by the client's codec, then it will be converted to the client version, testapi.Default.GroupVersion().String() in this test.
