Allow pods to access the kubernetes API via load balancers

It is expected that pods be able to use the Kubernetes API if they choose to do so for, for example, finding out which endpoints a service has, watch resources, etc. To that effect, the kubelet mounts a token for them to be able to talk to the API.

All the pods that do not run on hostnetworking run on our neutron networking. Being as it is, no pods with Neutron networking can access the Kubernetes API unless we make it accessible with Neutron load balancing.

This blueprint is for having pods like kube-dns, dashboard or the kuryr-controller itself have a K8s API loadbalancer in front of of the API to talk to
