Sync up between dev-1.18 and master branches (#19055)

* Fixed outdated ECR credential debug message (#18631)

* Fixed outdated ECR credential debug message

The log message for troubleshooting kubelet auto fetching ECR credentils issue has been changed (noticed since 1.14), and the new message reads like this when verbose log level is set to 3:

      - `aws_credentials.go:109] unable to get ECR credentials from cache, checking ECR API`
      - `aws_credentials.go:116] Got ECR credentials from ECR API for <Your ECR AWS Account ID>.dkr.ecr.us-east-1.amazonaws.com`

This is based on the kubelet source code: 
    https://github.com/kubernetes/kubernetes/blob/release-1.14/pkg/credentialprovider/aws/aws_credentials.go#L91

This PR is to fix this and to avoid confusion for more people who are troubleshooting the kubelet ECR issue.

* Correct description of kubectl (#18172)

* Correct description of kubectl

Given that `kubectl` is not a [command line interface (CLI)](https://en.wikipedia.org/wiki/Command-line_interface), I suggest calling it what it is -- a control utility (ctl = control). The term "tool" is commonly used in place of "utility," including the `kubectl` docs.

A CLI presents the user with a command prompt at which the user can enter multiple command lines that a command-line interpreter interprets and processes. Think of `bash`, `emacs`, or a SQL shell.  Since `kubectl` is not run in a shell, it is not a CLI.

Here are related docs that correctly refer to `kubectl` as a "command-line tool":

- https://kubernetes.io/docs/reference/tools/#kubectl
- https://kubernetes.io/docs/reference/glossary/?fundamental=true#term-kubectl
- https://kubernetes.io/docs/tasks/tools/install-kubectl/
- https://kubernetes.io/docs/reference/kubectl/kubectl/

* install container runtimes without prompts (#18893)

In Kubernetes docs, all of the packages that are required to set up the
Kubernetes are installed without requiring any prompts through
the package manager (like apt or yum) except for the container runtimes.

https://kubernetes.io/docs/setup/production-environment/container-runtimes/

So, it would be better to have these installations with prompts (yes) disabled.

When running the `kubectl patch` example, on Windows systems you get an
error when passing the patch request in single quotes. Passing it in
double quotes with the inner ones escaped produced the desired behavior
as is in the example given for Linux systems. I've added a small note
for Windows users to have that in mind.

I've removed the shell syntax from the Windows example and have changed
the description to be the same as the one used in

though it is note inside a note shortcode, therefore I've opted out of
using any syntax as it seems to break rendering inside the shortcode.

* Add cmd markdown syntax and fix order list

I've tested this locally with `make docker-serve` on my Linux machine
and finally things are looking better, I've managed to address these two

- the Windows example is now inside `note` shortcode and also the cmd
syntax renders correctly on the page

- the list of steps broke after the first one, I've indented a paragraph
and now the steps are in the expected order

### Pod Selector {#pod-selector}
`.spec.selector` 字段表示 Pod Selector,它与 [Job](/docs/concepts/jobs/run-to-completion-finite-workloads/) 的 `.spec.selector` 的作用是相同的。
从 Kubernetes 1.8开始,您必须指定与 `.spec.template` 的标签匹配的 pod selector。当不配置时,pod selector 将不再有默认值。selector 默认与 `kubectl apply` 不兼容。 此外,一旦创建了 DaemonSet,它的 `.spec.selector` 就不能修改。修改 pod selector 可能导致成为 孤儿Pod,并且这对用户来说是困惑的。

<!--
The `.spec.selector` is an object consisting of two fields:
* `matchLabels` - works the same as the `.spec.selector` of a [ReplicationController](/docs/concepts/workloads/controllers/replicationcontroller/).
* `matchExpressions` - allows to build more sophisticated selectors by specifying key,
list of values and an operator that relates the key and values.
When the two are specified the result is ANDed.
If the `.spec.selector` is specified, it must match the `.spec.template.metadata.labels`. Config with these not matching will be rejected by the API.
Also you should not normally create any Pods whose labels match this selector, either directly, via
another DaemonSet, or via other controller such as ReplicaSet. Otherwise, the DaemonSet
controller will think that those Pods were created by it. Kubernetes will not stop you from doing
this. One case where you might want to do this is manually create a Pod with a different value on
a node for testing.

* `matchLabels` - 与 [ReplicationController](/docs/concepts/workloads/controllers/replicationcontroller/) 的 `.spec.selector` 的作用相同。

如果指定了 `.spec.selector`,必须与 `.spec.template.metadata.labels` 相匹配。如果与它们配置的不匹配,则会被 API 拒绝。
此外,您通常不应该创建任何 pods,它们的 label 与 selector 匹配,或者直接创建,或者通过另一个 DaemonSet、或者其他控制器,比如 ReplicaSet。否则,DaemonSet 控制器会认为这些 Pod 是由它创建的。Kubernetes 不会阻止你这样做。 您可能希望这样做的一种情况是在节点上手动创建具有不同值的 Pod 以进行测试。
