Another question - are features that tooz support with etcd enough for
cinder active/active to work?

IIRC, for NFS openstack-ansible deploy in active/standby mode by default.
Only ceph goes "active/active" but we don't define coordination url for
that - only define cluster_name...
Though, we do provide a role/way to get etcd, so no blocker to get
coordination_url for cinder if etcd covers all cinder needs
