Switch pod eviction client from v1alpha1 to v1beta
Generated client 1.5 has a function to evict a pod. The function uses v1alpha1.Eviction object instead of v1beta1. This pr changes the api version that is being used.

fix issue in reconstruct volume data when kubelet restarts
During state reconstruction when kubelet restarts, outerVolueSpecName
cannot be recovered by scanning the disk directories. But this
information is used by volume manager to check whether pod's volume is
mounted or not. There are two possible cases:
1. pod is not deleted during kubelet restarts so that desired state
should have the information. reconciler.updateState() will use this
inforamtion to update.
2. pod is deleted during this period, reconciler has to use
InnerVolumeSpecName, but it should be ok since this information will not
be used for volume cleanup (umount)

Do not emit event for AlreadyExists errors
Fixes https://github.com/kubernetes/kubernetes/issues/36598 also reduced the clutter of events since the AlreadyExists error is a common error (may be a slow rs cache or a fast resync of the deployment that causes it apart from hash collisions)

Node Conformance & E2E: Get node name from node object.
This PR changes the node e2e test framework to get node name from apiserver instead of test flags.
When a user tried out the node conformance test, he found that node conformance test will not work properly if kubelet is started with `hostname-override`.
The reason is that node conformance test is using [the default node name - `os.Hostname`](https://github.com/kubernetes/kubernetes/blob/master/test/e2e_node/e2e_node_suite_test.go#L124), which may be different from `hostname-override`. This will cause test pods not scheduled, and eventually test timeout.
We can expose a flag from node conformance test, and let user set node name themselves if they are using `hostname-override` on kubelet. However, let the framework automatically detect it from apiserver is more user friendly.
/cc @kubernetes/sig-node
This PR 1) only changes node e2e test framework; 2) fixes a problem in node conformance test which is a 1.5 feature. @saad-ali Can we have this in 1.5?

README: stop linking to a 18 month old version
We are proud of the v1.0 release but lets give users context on the date
it was released and not drive them to the actual release since
they should be using the latest release instead.

Expand documentation and TODOs in a few packages
I was reading through unfamiliar code and mostly added TODOs and expanded and clarified documentations.
There are a couple of things that are real code changes:
- Removed some unused constants
- Changed `workqueue.Parallize` to clamp the number of worker goroutines to the number of items to be processed.
- Added another unit test to `workqueue.queue`. I thought I found a bug (I was wrong) and wrote a unit test to isolate. I figure the extra test is worth keeping.

CRI: general grammar/spelling/consistency cleanup
No semantic changes, but a lot of shuffling of docstrings to make things
more consistent. In particular, standardise on the zeroth-article (i.e.
prefer `// Version` to `// The version`) and ending all docstrings with
periods.
(This knowingly conflicts with #36446 and intentionally omits changing the
Annotations field - I'll rebase this or that respectively as necessary.)

Ensure proper serialization of updates and creates in federation test watcher
Fix for finalizer test problems. The issue there was that the updates were coming out of order. It was caused by firing updates in new goroutines in test watcher. The proper solution is to order them in a queue and fire in order on a single goroutine.

Fix getting cgroup pids
Fixes https://github.com/kubernetes/kubernetes/issues/35214, https://github.com/kubernetes/kubernetes/issues/33232
Verified manually, but I didn't have time to run all the e2e's yet (will check it in the morning).
This should be cherry-picked into 1.4, and merged into 1.5 (/cc @saad-ali )
```release-note
Fix fetching pids running in a cgroup, which caused problems with OOM score adjustments & setting the /system cgroup ("misc" in the summary API).

Add e2e node test for log path
fixes#34661
A node e2e test to check if container logs files are properly created with right content.
Since the log files under `/var/log/containers` are actually symbolic of docker containers log files, we can not use a pod to mount them in and do check (symbolic doesn't supported by docker volume).

Fix Docker Registry image version to 2.5.1
`registry:2` is constantly being updated with new versions. This means there's a possibility that the image may be changed unintentionally. For example, when the Pod is rescheduled on nodes that does not already have the image, depending on the time of the pull, `registry:2` may result in different images.
Fix this to the latest `registry:2.5.1` instead to avoid this problem.
