Kubernetes 1.10 snap tracks

[sparkiegeek]

Granting request for track 1.10 since the snaps have existing tracks and the new request conforms to the previous ones.

@cynerva

With that in mind, could we get 1.10 tracks created for the following snaps?

kubectl kube-apiserver kube-controller-manager kube-scheduler kubelet kube-proxy kubeadm kubefed kubernetes-test cdk-addons

All done, happy 1.10 hacking!
