Importing the `k8s.io/kubernetes/pkg/features` package in the remote runtime implementation makes it harder to separate the functionalities at some later point in time. We now decouple them by checking if the feature is enabled directly in the kubelet service creation path. Signed-off-by: Sascha Grunert <sgrunert@redhat.com>
