Davanum Srinivas c0d16c279a Get rid of zookeeper from devstack
In Ibbb430fb1dbf66942168e0cb52d990ab6a2eb8d7, we are adding
etcd3 as a new base service. We should drop zookeeper
and use etcd3 as the backend.

Since cinder is the first service for this tooz+etcd3 DLM
scenario and cinder uses eventlet we have cannnot use the
grpc based driver in tooz. So new CINDER_COORDINATION_URL
that defaults to the etcd3's grpc HTTP gateway based
tooz backend.

We need to hold this change until the tooz change (see
Depends-On) is available in a tooz release.
