the kubernetesservice controller is in charge of reconciling the
kubernetes.default service with the first IP in the service CIDR range
and port 443, it also maintains the Endpoints associated to the Service
using the configure EndpointReconciler.
Until now, the controller was creating the default namespace if it
doesn't exist , and creating the kubernetes.default service if it
doesn't exist too. However, it was polling the Service in each loop,
with this change we reuse the apiserver informers to watch the Service
instead of polling.
It also removes the logic to create the default network namespace, since
this is part of the systemnamespaces controller now.
