CLOUDSTACK-1414: Reduce arping time to nearly 0

Browse Source 
In the previous version it would take at least 1 seconds for arping, and it
would be big if the VR has more than 30 IPs - our biglock default timeout is 30
seconds.

Fix it by send out two arping immediately, and then sleep 1 second for router to
update arp cache.
