Description of problem:

When you enables the Openshift internal registry (integrated) to be 'Managed' it deploys a pod which holds an internal registry. This can be used by the OCP users to upload their images but it cannot be used as a Openshift Internal Registry to host:

- OCP Releases
- OLM Images

The technical reasons are:

- the registry doesn't support manifest lists (fat manifests)
- you cannot push manifest without a tag

This will be very useful for Edge cases like Telco and others.

Version-Release number of selected component (if applicable):

OCP 4.9 and earlier

How reproducible:

Always

Steps to Reproduce:

1. Enables the Integrated Registry (Managed) into the OCP Cluster config ([https://docs.openshift.com/container-platform/4.9/registry/configuring_registry_storage/configuring-registry-storage-baremetal.html](https://docs.openshift.com/container-platform/4.9/registry/configuring_registry_storage/configuring-registry-storage-baremetal.html))
2. Execute the commands to perform the sync (down bellow)
3. Wait until if fails (this does not fail at the beggining

Actual results:
