This is a temporary hack to bypass CRI when getting container logs or
running exec in a container. This is necessary to unblock testing and adding
other features in the integration.
Add a new docker integration with kubelet using the new runtime API.
This change adds the package with some skeletons, and implements some
of the basic operations.
