Mirror images from one repository to another

Example usage
  # Copy image to another tag
  oc image mirror myregistry.com/myimage:latest myregistry.com/myimage:stable

  # Copy image to another registry
  oc image mirror myregistry.com/myimage:latest docker.io/myrepository/myimage:stable

  # Copy all tags starting with mysql to the destination repository
  oc image mirror myregistry.com/myimage:mysql* docker.io/myrepository/myimage

  # Copy image to disk, creating a directory structure that can be served as a registry
  oc image mirror myregistry.com/myimage:latest file://myrepository/myimage:latest

  # Copy image to S3 (pull from <bucket>.s3.amazonaws.com/image:latest)
  oc image mirror myregistry.com/myimage:latest s3://s3.amazonaws.com/<region>/<bucket>/image:latest

  # Copy image to S3 without setting a tag (pull via @<digest>)
  oc image mirror myregistry.com/myimage:latest s3://s3.amazonaws.com/<region>/<bucket>/image

  # Copy image to multiple locations
  oc image mirror myregistry.com/myimage:latest docker.io/myrepository/myimage:stable \
  docker.io/myrepository/myimage:dev

  # Copy multiple images
  oc image mirror myregistry.com/myimage:latest=myregistry.com/other:test \
  myregistry.com/myimage:new=myregistry.com/other:target

  # Copy manifest list of a multi-architecture image, even if only a single image is found
  oc image mirror myregistry.com/myimage:latest=myregistry.com/other:test \
  --keep-manifest-list=true

  # Copy specific os/arch manifest of a multi-architecture image
  # Run 'oc image info myregistry.com/myimage:latest' to see available os/arch for multi-arch images
  # Note that with multi-arch images, this results in a new manifest list digest that includes only
  # the filtered manifests
  oc image mirror myregistry.com/myimage:latest=myregistry.com/other:test \
  --filter-by-os=os/arch

  # Copy all os/arch manifests of a multi-architecture image
  # Run 'oc image info myregistry.com/myimage:latest' to see list of os/arch manifests that will be mirrored
  oc image mirror myregistry.com/myimage:latest=myregistry.com/other:test \
  --keep-manifest-list=true

  # Note the above command is equivalent to
  oc image mirror myregistry.com/myimage:latest=myregistry.com/other:test \
  --filter-by-os=.*

  # Copy specific os/arch manifest of a multi-architecture image
  # Run 'oc image info myregistry.com/myimage:latest' to see available os/arch for multi-arch images
  # Note that the target registry may reject a manifest list if the platform specific images do not all
  # exist. You must use a registry with sparse registry support enabled.
  oc image mirror myregistry.com/myimage:latest=myregistry.com/other:test \
  --filter-by-os=os/arch \
  --keep-manifest-list=true
