Use kubeadm stable for systesting

This commit updated to use kubeadm stable for system testing, and
created a single base yaml file for contiv deployment, also created
a contiv-compose to update the base yaml file to support system testing,
prometheus, auth_proxy and ACI(not yet).
Update system testings to allow running netplugin on master nodes, so that
service like kube-dns and kube-dashboard could be created correctly.
Also formated ruby files and updated vagrant file so kube master could have
more memories.
