When cell computes do not have external_ids:ovn-remote configured
for OVN, it breaks.
Running manually:
ovs-vsctl set open . external_ids:ovn-remote="ssl:<ovn_dns_vip>:6642"
(or by DBs IPs) fixes it and ovn-controller connects the db and adds
the Chassis.
Fix multi-cell/multi-stack exports by also exporting ovn_dbs_node_ips.
So that when there is no ovn_dbs_vip data in hiera (i.e. no value for
t-h-t OVNDBsVirtualFixedIPs), there are still ovn_dbs_node_ips data to
have things configured properly for OVN on computes.
