// internal versioning scheme. This test verifies that two isolated schemes (Test, and api.Scheme)
// can be conjoined into a single output object.

// 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, latest.Version 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, latest.Version in this test.
