Bug Description

Replay parameters:
   - switch_heartbeat_time = 30
   - switch_replay_count = 3

While the Nexus switch is rebooting, delete the last VM of a tenant network.
     - VM fails to be deleted completely; in ERROR status.
     - mysql database entry does get removed.
     - Traceback is logged in server.log.
     - When the Nexus switch boots up, the replay code does not configured the VLAN associated with that network.
     - Have to issue the delete command again to cleanly remove the VM.
