When running `oc adm release extract --included --credentials-requests` on a 4.15 gcp cluster(baselineCapabilitySet: None+additionalEnabledCapabilities: MachineAPI CloudCredential) for a tobe-upgraded 4.16 release payload, the CR of the new caps in 4.16 is not extracted.

    # ./oc version
Client Version: 4.16.0-rc.2

    always

    1. set up a 4.15.15 cluster(None in baselineCapabilitySet + MachineAPI and CloudCredential in additionalEnabledCapabilities)
    2. run oc adm release extract to extract CR based above cluster for a 4.16.0-rc.3 release payload 
    3.     

    there is not the new-in-4.16 cap(CloudControllerManager, Ingress) CR.

    the new-in-4.16 cap(CloudCredential) CR should be extracted.

    after upgrade the cluster to 4.16, run `oc adm release extract --included --credentials-requests`, it will extract CR including the new caps.
