Thanks for working on this @dims (and @mattjmcnaughton)! I agree on the overall idea as discussed previously, and as a sig-node contributor it would also make "my life" a lot easier. It would also help making the codebase cleaner and easier to work with. 😄

Still need to read through and think about the details, but overall this looks good!

- flags that are used to configure dockershim.
- support to get container logs when docker uses journald as the driver.
- logic of moving docker processes to a given cgroup
- TBD anything else?
