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. Signed-off-by: Krisztian Litkey <krisztian.litkey@intel.com>
