Kube-Router - v2.0.0-rc6

Summary

Adds a new controller for kube-router which allows it to do IP address allocation for load-balancer type services. Previously, one had to use something like MetalLB for this functionality, now kube-router is able to handle this itself. See load-balancer allocation docs for more information.
