Leave the old implementation (dockertools/rkt) untouched so that
containers will not be restarted during kubelet upgrade. For CRI
implementation (kuberuntime), container restart is required for kubelet
upgrade.

dockertools: remove some dead code
Remove `dockerRoot` that's not used anywhere.
Enforce the following limits:
12kb for total message length in container status
4kb for the termination message path file
2kb or 80 lines (whichever is shorter) from the log on error
Fallback to log output if the user requests it.

dockertools/nsenterexec: fix err shadow
The shadow of err meant the combination of `exec-handler=nsenter` +
`tty` + a non-zero exit code meant that the exit code would be LOST
FOREVER 👻
This isn't all that important since no one really used the nsenter exec
handler as I understand it

Fix kubelet cross build
**What this PR does / why we need it**: Cross builds are not passing for MacOS and Windows. We are expecting Windows binaries for `kubelet` and `kube-proxy` to be released by the first time with 1.5.2 to be released later today.
**Which issue this PR fixes**:
fixes#39005fixes#39714
**Special notes for your reviewer**: /cc @feiskyer @smarterclayton @vishh this should be P0 in order to be merged before 1.5.2 and obviously fix the cross build.

The script does the import rewriting and gofmt. Then you do a build, codegen, bazel update, and it produces all the updates.
If we agree this is the correct approach. I'll create a verify script to make sure that no one messes with any files in the "dead" packages above.

Kubelet: add image ref to ImageService interfaces
This PR adds image ref (digest or ID, depending on runtime) to PullImage result, and pass image ref in CreateContainer instead of image name. It also
* Adds image ref to CRI's PullImageResponse
* Updates related image puller
* Updates related testing utilities
~~One remaining issue is: it breaks some e2e tests because they [checks image repoTags](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/framework/util.go#L1941) while docker always returns digest in this PR. Should we update e2e test or continue to return repoTags in `containerStatuses.image`?~~
Fixes#38833.

Support systemd based pod qos in CRI dockershim
This PR makes pod level QoS works for CRI dockershim for systemd based cgroups. And will also fix#36807
- [x] Add cgroupDriver to dockerService and use docker info api to set value for it
- [x] Add a NOTE that detection only works for docker 1.11+, see [CHANGE LOG](https://github.com/docker/docker/blob/master/CHANGELOG.md#1110-2016-04-13)
- [x] Generate cgroupParent in syntax expected by cgroupDriver
- [x] Set cgroupParent to hostConfig for both sandbox and user container
- [x] Check if kubelet conflicts with cgroup driver of docker

Wrong comment to describe docker version
The original comment about minimal docker version fo `room_score_adj` is wrong (though the code is right).
Really sorry for misleading :/
