dockershim: Fix the race condition in ListPodSandbox
In ListPodSandbox(), we
1. List all sandbox docker containers
2. List all sandbox checkpoints. If the checkpoint does not have a
corresponding container in (1), we return partial result based on
the checkpoint.
The problem is that new PodSandboxes can be created between step (1) and
(2). In those cases, we will see the checkpoints, but not the sandbox
containers. This leads to strange behavior because the partial result
from the checkpoint does not include some critical information. For
example, the creation timestamp'd be zero, and that would cause kubelet's
garbage collector to immediately remove the sandbox.
This change fixes that by getting the list of checkpoints before listing
all the containers (since in RunPodSandbox we create them in the reverse
order).

Only create the symlink when container log path exists
When using `syslog` logging driver instead of `json-file`, there will not be container log files such as `<containerID-json.log>`. We should not create symlink in this case.

Use namespace from context
Fixes#42653
Updates rbac_test.go to submit objects without namespaces set, which matches how actual objects are submitted to the API.

DaemonSet: Respect ControllerRef
**What this PR does / why we need it**:
This is part of the completion of the [ControllerRef](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/controller-ref.md) proposal. It brings DaemonSet into full compliance with ControllerRef. See the individual commit messages for details.
**Which issue this PR fixes**:
This ensures that DaemonSet does not fight with other controllers over control of Pods.
**Special notes for your reviewer**:
**Release note**:
```release-note
DaemonSet now respects ControllerRef to avoid fighting over Pods.
```

Add pprof trace support
Add support for `/debug/pprof/trace`
Can wait for master to reopen for 1.7.
cc @smarterclayton @wojtek-t @gmarek @timothysc @jeremyeder @kubernetes/sig-scalability-pr-reviews
The design of DaemonSet requires a relist before each phase (manage,
update, status) because it does not short-circuit and requeue for each
action triggered.
The DaemonSet Listers still use selectors, because this is the
behavior expected by callers. This clarifies the meaning of the
returned list. Some callers may need to switch to using
GetControllerOf() instead, but that is a separate, case-by-case issue.
* Properly return ImageNotFoundError
* Support inject "Images" or "ImageInspects" and keep both in sync.
* Remove the FakeDockerPuller and let FakeDockerClient subsumes its
functinality. This reduces the overhead to maintain both objects.
* Various small fixes and refactoring of the testing utils.

Pods pending due to insufficient OIR should get scheduled once sufficient OIR becomes available (e2e disabled).
#41870 was reverted because it introduced an e2e test flake. This is the same code with the e2e for OIR disabled again.
We can attempt to enable the e2e test cases one-by-one in follow-up PRs, but it would be preferable to get the main fix merged in time for 1.6 since OIR is broken on master (see #41861).

Remove everything that is not new from batch/v2alpha1

@lavalamp you've asked for it
@erictune this is a prereq for moving CronJobs to beta. I initially planned to put all in one PR, but after I did that I figured out it'll be easier to review separately. ptal

provide active pods to cgroup cleanup
**What this PR does / why we need it**:
This PR provides more information for when a pod cgroup is considered orphaned. The running pods cache is based on the runtime's view of the world. we create pod cgroups before containers so we should just be looking at activePods.
**Which issue this PR fixes**
Fixes https://github.com/kubernetes/kubernetes/issues/42431

cgroup names created by kubelet should be lowercased
**What this PR does / why we need it**:
This PR modifies the kubelet to create cgroupfs names that are lowercased. This better aligns us with the naming convention for cgroups v2 and other cgroup managers in ecosystem (docker, systemd, etc.)
See: https://www.kernel.org/doc/Documentation/cgroup-v2.txt
"2-6-2. Avoid Name Collisions"
**Special notes for your reviewer**:
none
**Release note**:
```release-note
kubelet created cgroups follow lowercase naming conventions
```
