e2e: Ensure that sysrq-trigger is enabled before use

**What this PR does / why we need it**:

On Ubuntu (and, presumably, other distros too), the default configuration prohibits some sysrq operations.  Before performing sysrq operations in the e2e testing, ensure that all operations are permitted.

Make admission webhooks conversion convert CONNECT body correctly

Fix #59759.

1. Make apiserver pass connectRequest.Options directly to the admission layer. All other information in rest.ConnectRequest is present in admission attributes.
2. Make the scope.Kind of pod/attach, pod/exec, pod/portforward, node/proxy, service/proxy to their respective options Kind, instead of the parent Kind.

I've tested it locally, the conversion is working correctly for "kubectl attach". I'll add e2e tests.

I'll keep this to myself until I add the tests, but cc @mikedanese @liggitt RE. https://github.com/kubernetes/kubernetes/pull/66633.

Use the same pattern used everywhere in the e2e test

document /watch prefix deprecation

closes #65133

these have been marked as deprecated in code for many releases, and all client accesses have switched to using the ?watch=true access method, but documentation was never updated

@kubernetes/sig-api-machinery-api-reviews @kubernetes/api-reviewers

```release-note
The watch API endpoints prefixed with `/watch` are deprecated and will be removed in a future release. These standard method for watching resources (supported since v1.0) is to use the list API endpoints with a `?watch=true` parameter. All client-go clients have used the parameter method since v1.6.0.

Explicitly disable dry run for connect

**What this PR does / why we need it**:
It isn't clear whether or not dry run would work on connect. I think we should explicitly disable it so no one can try to dry run a connect request and accidentally open a connection.

**Release note**:
```release-note
kube-apiserver: setting a `dryRun` query parameter on a CONNECT request will now cause the request to be rejected, consistent with behavior of other mutating API requests. Examples of CONNECT APIs are the `nodes/proxy`, `services/proxy`, `pods/proxy`, `pods/exec`, and `pods/attach` subresources. Note that this prevents sending a `dryRun` parameter to backends via `{nodes,services,pods}/proxy` subresources.

Support dry run in admission plugins

**What this PR does / why we need it**:
Adds support for dry run to admission controllers as outlined by https://github.com/kubernetes/community/pull/2387

- [x] add IsDryRun() to admission.Attributes interface
- [x] add dry run support to NamespaceAutoProvision
- [x] add dry run support to ResourceQuota
- [x] add dry run support to EventRateLimit

The following is being done in a follow up PR:
- [x] add DryRun to ```admission.k8s.io/v1beta1.AdmissionReview```
- [x] add DryRunnable to ```admissionregistration.k8s.io/v1beta1.(Valid|Mut)atingWebhookConfiguration```
- [x] add dry run support to (Valid|Mut)atingAdmissionWebhook

/sig api-machinery

**Release note**:
```release-note
In clusters where the DryRun feature is enabled, dry-run requests will go through the normal admission chain. Because of this, ImagePolicyWebhook authors should especially make sure that their webhooks do not rely on side effects.
```

Here is a list of the admission controllers that were considered when making this PR:
- AlwaysAdmit: No side effects
- AlwaysPullImages: No side effects
- LimitPodHardAntiAffinityTopology: No side effects
- DefaultTolerationSeconds: No side effects
- AlwaysDeny: No side effects
- EventRateLimit: Has side possible effect of affecting the rate, skipping this entire plugin in dry-run case since it won't correspond to an actual write to etcd anyway
- DenyEscalatingExec: No side effects
- DenyExecOnPrivileged: Deprecated, and has no side effects
- ExtendedResourceToleration: No side effects
- OwnerReferencesPermissionEnforcement: No side effects
- ImagePolicyWebhook: No side effects* (*this uses a webhook but it is very specialized. It only sees pod container images, for the purpose of accepting or rejecting certain image sources, so it is very unlikely that it would rely on side effects.)
- LimitRanger: No side effects
- NamespaceAutoProvision: Has possible side effect of creating a namespace, skipping the create in the dry-run case
- NamespaceExists: No side effects
- NodeRestriction: No side effects
- PodNodeSelector: No side effects
- PodPreset: No side effects
- PodTolerationRestriction: No side effects
- Priority: No side effects
- ResourceQuota: Has side possible effect of taking up quota, will only check quota but skip changing quota in the dry-run case
- PodSecurityPolicy: No side effects
- SecurityContextDeny: No side effects
- ServiceAccount: No side effects
- PersistentVolumeLabel: No side effects
- PersistentVolumeClaimResize: No side effects
- DefaultStorageClass: No side effects
- StorageObjectInUseProtection: No side effects
- Initializers: No side effects
- NamespaceLifecycle: No side effects
- MutatingAdmissionWebhook: Same as below
- ValidatingAdmissionWebhook: Has possible side effects depending on if webhook authors depend on side effects and a reconciliation mechanism. To fix this we will expose whether or not a request is dry-run to webhooks through AdmissionReview, and require that all called webhooks understand the field by checking if DryRunnable true is specified in the webhook config. This will be done in a separate PR because it requires an api-change

Makes kubectl wait exit with status 1 and print an error message, if there is no resources matching selectors

**What this PR does / why we need it**:

It makes the `kubectl wait` command print an error message and exit with exit code 1, if there is no resource matching users's query. This can happen when user specifies selectors. Example:

```
kubectl wait deployment -l app=something-that-does-not-exist --for condition=available --timeout=5s
```

**Which issue(s) this PR fixes**:
Fixes #66456

**Special notes for your reviewer**:

This is my first contribution into the project (except one line change in docs) and don't have much experience with Go. I learned a lot while working on this (about resource finders and the `Visitor` interface and it's implementations), but it is very likely that I'm doing something wrong :)

I'm keen to continue contributing into the project (into the cli part for now), so I will really appreciate detailed feedback, if you have a chance to provide it (point me into a right direction and/or explain why it's not a good idea to do something in a certain way).

Thanks!

**Release note**:
```release-note
kubectl: the wait command now prints an error message and exits with the code 1, if there is no resources matching selectors
```
