install/kube-up: fix some errors while install k8s through kube-up/down.sh

What this PR does / why we need it:

     etcd2.3.1 will be installed follow this scripts, but k8s use etcd3 as default storage backend, so the next error will always be apprear: 
     API server: rpc error: code = 13 desc = transport is closing
     so i think we should change the version of etcd

    thank you!
