We revert I0d9eb663405d1113ea84e3c12651a3f0dbdfc75d and we instead
export ovn_dbs_vip on all nodes so it can be used in cells. Reason for this
is that we want a separate VIP for OVN because a) composable roles and b)
we do not want to impose the extra promote master constraints on the internal_api
VIP which ends up being used by OVN.
In the same vein as I7ca94dff4acf0816708110b9fe6f78d19dcc7b4d
(Move redis_vip to all_nodes.j2) we will have the ovn_dbs_vip moved
to all nodes (via I1d80587752ffca6c3eb5281aa89ea3d7cf5535ce).
