The kubeadm defaults in features.go differ between versions.
e2e_kubeadm tests cannot import the kubeadm features.go,
or easily detect the versioned of the kubeadm binary used
to create the cluster.
Check for the existence of both versioned and unversioned
objects independent of the value of the FG. Once the FG
goes GA only the unversioned objects should be checked.
Without this change kubeadm e2e skew tests will fail where kubeadm
is at 1.24 (has the FG defaulted to true), the FG is not
explicitly set by the user and the k8s version is at 1.23.
