Add feature to mirror Quay.io (http://quay.io/) and GCR images to Public ECR repos

[alolita]

I’d like to have the ability to use docker-mirror to support mirroring of non-Docker repo images from Quay container registry and Google Container Registry (GCR) to be published in public ECR repos.

An example YAML file would look as follows:

target:
  registry: ACCOUNT_ID.dkr.REGION.amazonaws.com
  prefix: "hub/"
repositories:
  - name: quay.io/opentelemetry/opentelemetry-operator
      - "v*"

  - name: gcr.io/kubebuilder/kube-rbac-proxy
      - max_tags: 10

We are working on an enhancement which we plan to contribute to the project.

@Saber-W there is no need to assign anything, just work on the issue and we'll review the PR.

Mirroring any registry would be great really since it would be useful to be able to pull things locally in event of outages from other public registries. Though thanks for Quay/GCR.

I think we normally support docker registry v2, but some registries do awkward things. Do you have registries that don't work here @bkrugerp99 ?

Closing issue since this is completed. Ty for reviewing and merging.
