What this PR does / why we need it:

Since openYurt is fully supports the k8s v1.22 This project should support it as well.

Which issue(s) this PR fixes:

Fixes: https://github.com/openyurtio/openyurt/issues/680

What does this pr include:

From v1.22 ChangeLog, we can see: It removes :

• The beta CustomResourceDefinition API (apiextensions.k8s.io/v1beta1)
• Beta versions of the ValidatingWebhookConfiguration and MutatingWebhookConfiguration API (the admissionregistration.k8s.io/v1beta1 API versions)

To support k8s v1.22. I have to upgrade our crd and webhook.

• To support crd from apiextensions.k8s.io/v1beta1 -> apiextensions.k8s.io/v1. Have done:

     Add "crd:crdVersions=v1" to controller-gen cmd in Makefile line 77.

• To support webhook from admissionregistration/v1beta1 -> admissionregistration/v1. Have done:

     1. Use "v0.5.0-kruise-beta.3" to parse and generate v1 webhook. Makefile line 111
  
     2. Add sideEffects=none,admissionReviewVersions=v1, at the end of "// +kubebuilder:webhook"
     Those two keys are required in v1. Affected lots of files: 
     grep -rln 'kubebuilder:webhook' *
  
     3. "k8s.io/api/admissionregistration/v1beta1" -> "k8s.io/api/admissionregistration/v1"
     affected file:
     - pkg/yurtappmanager/webhook/util/controller/webhook_controller.go
     - pkg/yurtappmanager/webhook/util/configuration/configuration.go
  
     4. add "// +kubebuilder:pruning:PreserveUnknownFields" to DeploymentTemplateSpec.metav1 and StatefulSetTemplateSpec.metav1
     Otherwise it’s content will be ignored
  
     5. manually update file: config/yurt-app-manager/webhook/patch_manifests.yaml 
     set to v1

• Run make generate-manifests regenerate crd and webhook yaml

   modified:   config/yurt-app-manager/crd/bases/apps.openyurt.io_nodepools.yaml

• Run make generate-deploy-yaml and cat _output/yamls/yurt-app-manager.yaml > config/setup/all_in_one.yaml

   Attention:  image generate is openyurt/yurt-app-manager:d79a9f0
   we have to upload one, then update this config.

• Finally, update hack/lib/release-images.sh to accelerate debug build time

     add mount volume: "-v ${GOPATH}:/go"

Hi, @adamzhoul: @huiwq1990 submitted a PR to support k8s 1.22 for yurt-app-manager before: https://github.com/openyurtio/yurt-app-manager/pull/49 I checked both of your PRs and found that your changes differ much with each other, so could you please cross review with @huiwq1990 and submit an unified PR after your discussion? Thanks!

@adamzhoul @zzguang I think the most important is we should change to go.mod file. This PR does not upgrade k8s dependence to 1.22.3.

@zzguang @huiwq1990 @rambohe-ch thanks for the review

@huiwq1990 I think the update in https://github.com/openyurtio/yurt-app-manager/pull/49 contains updates here and more. so, I think we can close pr here.

But, pr #49 should be merged soon.
