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!
