Add a common NRI 'service' plugin. It takes care of relaying
requests and respones to and from NRI (external NRI plugins)
and the high-level containerd namespace-independent logic of
applying NRI container adjustments and updates to actual CRI
and other containers.
The namespace-dependent details of the necessary container
manipulation operations are to be implemented by namespace-
specific adaptations. This NRI plugin defines the API which
such adaptations need to implement.

Some minor improvements, but biggest for here is ErrPipeListenerClosed
is no longer an errors.New where the string matches the text of the now
exported net.ErrClosed in the stdlib, but is just assigned to net.ErrClosed
directly. This should allow us to get rid of the string check for "use of closed
network connection" here now..
