Kevin Carter 4745e709f6 Removes over zealous arp cache flushing
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.
