Issue MESOS-2574: Namespace handle symlinks in port_mapping isolator should not be under /var/run/netns
Consider putting symlinks under /var/run/messo/netns. This is because 'ip' command assumes all files under /var/run/netns are valid namespaces without duplication and it has command like: ip -all netns exec ip link to list all links for each network namespace.
