We can resubmit the packet against the flow table to get simplier result. Now we don't need to check if VM is in the same host as DHCP server or not.
Start/stop vm/dhcp server are done. Not done with VM migration. A new command(PvlanSetupCommand) is sent for setting up PVLAN for vms. Currently it's focus on OVS implementation. Need to be more abstruct and add vSwitch part.
