Remove hairpin nat on veth create

Writing to this file within /sys is casuing some issues for
older kernels, specifically with 2.6.xx, where the write is failing
because /sys is becoming ro.  We will continue to work on the 2.6 issues
but for the time being we cannot ship this with it enabled as it's
breaking all container runs.

Add call to label to allow it to tell kernel how to label created files

SELinux supports a call that tells the kernel, from this point onward

Add container spec

This document specifies the current container specification with all the
underlying setup and configuration that goes into making a container.
This is the v1 spec that is today but allows for flexability when we
introduce more features such as seccomp default profiles and more.
