[M00nF1sh]

Multiple changes around webhook and CRD yamls.

Webhooks

1. we use v1beta1 as our webhook version to support version <1.6.0.
2. Add two webhook for TargetGroupBinding:
   1. TargetGroupBindingMutator:
      • if spec.targetType unspecified, set it according to targetGroup in AWS.
   2. TargetGroupBindingValidator:
      • validate that spec.targetType are set.
      • validate that spec.targetType and spec.targetGroupARN are not mutated.
3. added "ARN" and "TARGET-TYPE" to be displayable fields for TargetGroupBinding CRD
4. enable status field of targetGroupBinding CRD.

CRD

1. we use v1beta1 as our webhook version to support version <1.6.0.
2. we make trivialVersions==false, since version<1.13 is not longer supported.

Makefile

1. upgrade controller-tools to be 0.4.0
2. use yq to substitute the generate webhook names from mutating-webhook-configuration and validating-webhook-configuration to be just webhook
   • yq w -i config/webhook/manifests.yaml -d'*' "metadata.name" "webhook"
   • on macOS, yq can be installed via brew install yq

ControllerYAML

1. added a patch to inject fsGroup: 1337 to make controller available for IAM-FOR-SA feature.
