Migrate to CRI container log format

[nwneisen]

This change makes cri-dockerd output logs in CRI format instead of json-file format. This fixes the #213 and bumps integration test's pinned SHA so they now include these tests.

cri-docker previously had no interaction with the container logs. It would only create a symlink from the dockerd output path to the location expected by kube. This change now tails the logs created by dockerd, formats them to CRI, and creates a separate file in the log location expected by kube.
