Comment 1 for bug 1462107

Symptom:
   If the network node is rebooted,

       the following would be affected:
          1) creation of new VMs on tenant networks that existed prior to network
              node reboot would not get their VLAN config on the switch
     - Since the dhcp namespaces for these networks are already created
     after the reboot.

       the following would be unaffected:
          1) any existing VMs
              - since the tenant network's VLAN has already been configured on the switch
          2) any new VMs created on tenant networks already having VMs
              - since the tenant network's VLAN has already been configured on the switch
          3) any new tenant networks and their VMs created after the network node is back

Cause:
 Upon boots up, the dhcp namespace is created while the DB is still empty
   - VM triggered namespace creation is path where Nexus plugin configures the
      VLAN
