Give developer more help info when running integration tests without etcd found.
**What this PR does / why we need it**:
When running integration tests, if etcd version on env is lower than expected, developer will get info `You can use 'hack/install-etcd.sh' to install a copy in third_party/.` It would be better to have the same info if no etcd installed on env.
