    Update to push system images under the default registry namespaces

    Currently, if a system is installed with private registry, the
    image will be pushed to the local registry with the prefix of
    private registry url.

    For exmaple,
    k8s.gcr.io alternative registry => privateregistry.com/k8s.gcr.io

    k8s.gcr.io/kube-apiserver:v1.16.2
    => registry.local:9001/privateregistry.com/k8s.gcr.io/kube-apiserver:v1.16.2

    This commit updates to push system images to the original default
    registry namespace which doesn't include the private registry url.

    For example,
    k8s.gcr.io/kube-apiserver:v1.16.2
    => registry.local:9001/k8s.gcr.io/kube-apiserver:v1.16.2

    This update makes the system images download/pushing mechanism to
    align with the application images.
