This PR adds a GitHub workflow for building and publishing KinD node images on ghcr.io/fluxcd/kindest/node for a given Kubernetes git tag.
Motivation
This allows us to run the Flux benchmarks and conformance tests for Kubernetes pre-releases and stable versions without depending on the official KinD images which lag behind upstream releases and don't contain alpha, beta and RC builds.
Specifications
The KinD node images hosted on the FluxCD GitHub Container Registry are not multi-arch, instead we publish dedicated tags for each architecture in the format
<K8S-SEMVER>-<ARCH>.AMD64 images
Image format:
ghcr.io/fluxcd/kindest/node:<K8S-SEMVER>-amd64Builder: ubuntu-latest-16-cores (GitHub hosted runner)
ARM64 images
Image format:
ghcr.io/fluxcd/kindest/node:<K8S-SEMVER>-arm64Builder: c3.large.arm64 (Equinix Metal self-hosted runner)
