"contrail-rndc -c /etc/contrail/dns/contrail-rndc.conf reconfig"
can be used to update the contrail-named.conf and apply configs, but these configs
are not saved as we apply add new vdns etc., hence the script so both new configs(i,e views and zones) can be applied and older configurations for under options{} , key {}, logging {}, controls()
stanzas can be replayed on top.
