The grafana-operator creates Grafana pods from docker.io/grafana/grafana,
which the dockerhub remote did not allow, so the pods would ImagePullBackOff.
Add the ^grafana/ pattern so the grafana image (and image-renderer) proxy
through artifactapi.
ArtifactAPI now serves local docker repos as real container registries and the
provider exposes an artifactapi_local_docker resource, but this config had no
way to declare one.
- Add a local_docker variable, module resource, config loader wiring, and
terragrunt input, mirroring the other local_* kinds.
- Declare a docker-internal registry.
- Expand the README to cover the local_* and virtual kinds.
Depends on a terraform-provider-artifactapi release exposing
artifactapi_local_docker (and a matching .terraform.lock.hcl bump) before apply.
