PVLAN: Add pvlan in createNetworkCommand
Implement PVLAN on Xen

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.
PVLAN: Simplify OVS policy

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.
PVLAN: Remove bridge parameter in PvlanSetupCommand

Bridge is hypervisor dependent, shouldn't appear in PvlanSetupCommand.
PVLAN: Add network label parameter to PvlanSetupCommand

We need it to find the real bridge/switch to program on the OVS.

CLOUDSTACK-2085: VM weight on xen remain same as before vmscaleup ;because "Add-To-VCPUs-Params-Live.sh" is not getting copied on xs host
Fixed by updating the patch files that has
 entries to copy scipts on xenserver. Here we added
 Add-To-VCPUs-Params-Live.sh

Added a check on Host params whether host restricts Dynamic memory control(DMC) to able to allow scale up VM.
If DMC is not enabled then static max and min are set to SO.
