Comment 2 for bug 1541105

Looks like we're running into a bug from the older version of etcdctl on the atomic image. The pre-built image has 2.0.10, but if I update to 2.2.25 everything works correctly.

I haven't narrowed it down to be sure, but I think the bug was fixed in one of these commits:
473207a requests.go: always stop retrying after some attempts
5d62264 requests.go: fix not retry for doing request error
1d96359 requests.go: alwasy retry when failing to get response

It looks like with 2.0.10, if etcd isn't up, 'ls' will hang. We should upgrade to 2.2.25 at least for this polling call to etcdctl.
