deploy.sh and rollback.sh fixes (#99)

Browse source 
* Don't overwrite KUBECONFIG.

kubectl already knows to look in $HOME/.kube or use $KUBECONFIG.

https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/#set-the-kubeconfig-environment-variable

* Use $DIR instead of pwd.

* chmod +x kubernetes/rollback.sh
