This commit removes the use of the net-cache flushing from all $service plays which ensures that the cache is not overly flushed which could impact performance of services like neutron. The role lxc-container-destroy role was removed because its not used and if it were ever used it its use would result in the same situation covered by this issue. Additionally it was noted that on container restarts, the mac addresses of the container interfaces change. If *no* flushing is done at all, this results in long run times whilst the arp entry for the container IP times out. Hence, we add in here a configuration option that causes a gratuitous arp whenever an interface has it's mac set, and/or the link comes up. Because of the way the container veths work, we can't rely on that happening on a linkm up event. So we forcefully set the mac address in the post-up hook for the interface to force the issue of the gratuitous arp.
