Other components support set log level dynamically
**What this PR does / why we need it**:
#63777 introduced a way to set glog.logging.verbosity dynamically.
We should enable this for all other components, which is specially useful in debugging.
**Release note**:
```release-note
Expose `/debug/flags/v` to allow kubelet dynamically set glog logging level. If want to change glog level to 3, you only have to send a PUT request like `curl -X PUT http://127.0.0.1:8080/debug/flags/v -d "3"`.

Remove defaulting from shared ComponentConfig types
**What this PR does / why we need it**:
As @deads2k commented in kubernetes/community#2354, we should not register defaults for the shared componentconfig types as it gets very hard for consumer to opt-out of the default defaulting funcs. Instead, the package provides a `DefaultFoo` function the consuming API group can call if it wants to as an opt-in in `SetDefaults_Bar` (where `Bar` wraps `Foo` as a field)

1. Add cfssl/cfssljson ot the required bins for saving
2. Manually cloned/checked out the new dependencies to my gopath. `godep restore` doesn't pull them down because they aren't required or already in the `Godeps.json`. Used @BenTheElder's list here: https://github.com/kubernetes/kubernetes/issues/66995#issuecomment-410594532
3. `hack/godep-save.sh` to add the packages and dependencies to godep
4. Fixed two bugs when building:
a. `golang.org/x/crypto` needed to be updated
b. `github.com/cloudflare/cfssl` needed to be updated to 56268a613a so we can vendor their fork of `crypto/tls`, as we discard their modified vendored stdlib.
5. Update staging godeps
6. Update the `kube::util::ensure-cfssl` to install from vendor

Write manually-created conversion funcs for shared ComponentConfig types
**What this PR does / why we need it**:
Due to how `conversion-gen` works today, it only discovers manually-generated conversion functions when creating autogenerated content for a referencing package. So in the example of `pkg/apis/componentconfig` referencing `k8s.io/apiserver/pkg/apis/config` types, no "native" conversion functions will be called from `pkg/apis/componentconfig/v1alpha1/zz_generated.conversion.go` unless these `Convert_*` functions exist in `k8s.io/apiserver/pkg/apis/config/v1alpha1/`.
We might consider this a bug in `conversion-gen`, I don't know, but to unblock the process of moving componentconfigs out of `pkg/apis/` I'm sending this PR so https://github.com/kubernetes/kubernetes/pull/66722 eventually can merge.

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.

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

Percent-encode illegal characters in user.Info.Extra keys
This percent-encodes characters in `X-Remote-Extra-` and `Impersonate-Extra-` keys which aren't valid for header names per [RFC 7230](https://tools.ietf.org/html/rfc7230#section-3.2.6) (plus "%" to avoid breaking keys which contain them). The API server then blindly unescapes these keys.
Reviewer note:
Old clients sending keys which were `%`-escaped by the user will have their values unescaped by new API servers. New clients sending keys containing illegal characters (or "%") to old API servers will not have their values unescaped. This version skew incompatibility is a compromise discussed in #63682.
Fixes#63682

**Release note**:
```release-note

There's code to automatically populate OpenAPI info based on existing

extend timeout to workaround slow arm64 math
**What this PR does / why we need it**:
The math/big functions are slow on arm64. There is improvement coming
with go1.11 but until such time as that version can be used to build releases,
if a server uses rsa certificates on arm64, the math load for the multitude
of watches over-taxes the ability of the processor and the TLS connections
time out. Retries will also not succeed and serve to exacerbate the problem.
By extending the timeout, the TLS connections will eventually be
successful and the load will drop.

Add a new conversion path to replace GenericConversionFunc
reflect.Call is very expensive. We currently use a switch block as part of AddGenericConversionFunc to avoid the bulk of top level a->b conversion for our primary types which is hand-written. Instead of having these be handwritten, we should generate them.
The pattern for generating them looks like:
```
scheme.AddConversionFunc(&v1.Type{}, &internal.Type{}, func(a, b interface{}, scope conversion.Scope) error {
return Convert_v1_Type_to_internal_Type(a.(*v1.Type), b.(*internal.Type), scope)
})
```
which matches AddDefaultObjectFunc (which proved out the approach last year). The
conversion machinery should then do a simple map lookup based on the incoming types and invoke the function. Like defaulting, it's up to the caller to match the types to arguments, which we do by generating this code. This bypasses reflect.Call and in the future allows Golang mid-stack inlining to optimize this code.
As part of this change I strengthened registration of custom functions to be generated instead of hand registered, and also strengthened error checking of the generator when it sees a manual conversion to error out. Since custom functions are automatically used by the generator, we don't really have a case for not registering the functions.
Once this is fully tested out, we can remove the reflection based path and the old registration methods, and all conversion will work from point to point methods (whether generated or custom).
Much of the need for the reflection path has been removed by changes to generation (to omit fields) and changes to Go (to make assigning equivalent structs easy).

track schemes by name for error reporting
Getting an error message about a type not being in the scheme is hard to fix if you don't know which scheme is failing. This adds a name to the scheme which can be set during creation or can be set based on the calling stack. If you use the old constructor a name is generated for you based on the stack. Something like "k8s.io/client-go/dynamic/scheme.go:28" for instance.
Also moves a typer to its point of use. This was debt from previous refactors which I noticed going through.

Add additional authorization check for create-on-update
**What this PR does / why we need it**:
Currently it is possible for a user who is only authorized to update objects to send a PUT request for an object that doesn't currently exist, and if that resource allows create on update, it will all them to create the object. This PR fixes that bug and adds a test case which fails on master, but succeeds when the additional authorization check is done.
/sig api-machinery
/kind bug
/cc @liggitt @lavalamp
**Release note**:
```release-note
LimitRange and Endpoints resources can be created via an update API call if the object does not already exist. When this occurs, an authorization check is now made to ensure the user making the API call is authorized to create the object. In previous releases, only an update authorization check was performed.
