If the BACKUP_MIGRATION_IP is set to a different IP outside of
the default nets[1] set in the “openstack overcloud backup”
playbook setup_nfs role[2]. Then the NFS will fail to mount
directories during the backup, because they will not be
reachable | permitted.
This change simply adds a new variable
BACKUP_MIGRATION_CTL_PLANE_CIDRS into the ovn_migration script
to allow the user to overwrite the extra-var used for
Openstack overcloud backup --setup-nfs command.
