Thanks for sending this out.  However, in light of the discussion in
the patchset's cover letter it looks like we need to better support
nested container orchestrators which is likely going to require some
non-trivial changes to the kernel/userspace API.  Because of this I'm
going to hold off pulling these patches into a "working" branch,
hopefully the next revision of these patches will solve the nested
orchestrator issue enough that we can continue to move forward with
testing.
