CLOUDSTACK-3451 Parallel deployment - Xenserver - When deploying 30 Vms in parallel, some of the Vm deployment fails when “applying dhcp entry/applying userdata and password entry on router” and retry eventually happens when they succeed.

Changes:
- Passing the avoid set generated by the first pass of deployment to the second try.
- The second try is done, when the first pass that uses a reserved plan fails to deploy on the reserved host, to search over the entire zone again
