Mount iptables lock file in weave-kube (#3134)
Mount iptables lock file in weave-kube iptables uses the file `/run/xtables.lock` so that if changes are under way, another instance of the iptables command can wait till it is finished. We need to mount the lock file from the host to the container in order for this mechanism to work at all. Note we rely on kubelet touching the file before running any pods - see kubernetes/kubernetes#47212
