Add a call out to arping whenever an IP is assigned to the public interface (happens on CC failover, instance restoration, and elastic IP assignment).  Th\
e callout broadcasts an unsolicit
ed ARP message to the network which should cause servers/network devices on that network to flush and renew their ARP caches for the assigned IP.

    Fixes: EUCA-2973 EUCA-3450
add a timewait after arping call, with a comment to evaluate whether to wait() at all
