Use ko to build images (#4366)
This updates Makefile targets to build images using `docker buildx
build` to use `ko build` instead.

End-to-end tests are accomplished by building and loading the image
directly into the KinD cluster via ko.

Also:
- use GitHub Actions token to push to ghcr.io (setup-ko sets this up for us)
- allow forks to push to their forked repo's packages (useful for testing)

Developer Instructions

Building and publishing an image locally

First, make sure you install ko

Publishing to your local Docker daemon

Set the KO_DOCKER_REPO environment variable to ko.local:

KO_DOCKER_REPO=ko.local

Then build and publish an image:

ko build ./cmd/kyverno --preserve-import-paths

The image will be available locally as ko.local/github.com/kyverno/kyverno/cmd/kyverno.

Publishing to a local KinD cluster

First, create your KinD cluster:

kind create cluster

Set the KO_DOCKER_REPO environment variable to kind.local:

KO_DOCKER_REPO=kind.local

Then build and publish an image:

ko build ./cmd/kyverno --preserve-import-paths

This will build and load the image into your KinD cluster as:

kind.local/github.com/kyverno/kyverno/cmd/kyverno

If you have multiple KinD clusters, or created them with a non-default name, set KIND_CLUSTER_NAME=<your-cluster-name>.

Publishing to a remote registry

Set the KO_DOCKER_REPO environment variable to the registry you'd like to push to: For example:

KO_DOCKER_REPO=gcr.io/my-project/kyverno
KO_DOCKER_REPO=my-dockerhub-user/my-dockerhub-repo
KO_DOCKER_REPO=<ACCOUNTID>.dkr.ecr.<REGION>.amazonaws.com

Then build and publish an image:

ko build ./cmd/kyverno

The output will tell you the image name and digest of the image you just built.
