Support Kubernetes 1.8.0

[robhamk]

I use homebrew to install minikube which version is v0.22.2. The command is "brew cask install minikube"
My kubectl is the latest version 1.8.0. I installed it via "brew install kubectl"
Everything was going to fine but...
When I started to run minikube start --vm-driver=xhyve
Invalid Kubernetes version.
The following Kubernetes versions are available:
- v1.7.5
- v1.7.4
- v1.7.3
- v1.7.2
- v1.7.0
...
Does it mean minikube supports v.1.7.5 only?

You can try different Kubernetes versions with the experimental kubeadm bootstrapper. The following works for me:

minikube start --kubernetes-version v1.7.7 kvm --bootstrapper kubeadm

But there is on open issue for running v1.8.0 this way: #2018

Need 1.8.0 for kubernetes/kubernetes#28918

This was merged in #2060. We'll get a release and build out soon.
