only for master node with remote option when using load balancer to manage
ovndb clusters via pacemaker.
This is will allow setting inactivity probe on the masters.
For pacemaker to manage ovndb resources via LB, we skipped creating connection
table and hence the inactivity probe was getting set to 5000 by default.
In order to over-ride it we need this table. However, we need to skip slaves
listening on local sb and nb connections table so that LB feature is
intact and only master is listening on 0.0.0.0
e.g --remote=db:OVN_Southbound,SB_Global,connections and
--remote=db:OVN_Northbound,NB_Global,connections
will only be set on master node when using load balancer for sb and nb dbs
respectively.
