oc-mirror does not allow the mirroring of multiple ACM operator versions

4.16.z    

Always    

1.  Create an ImageSetConfiguration

```
  operators:
  - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.14
    packages:
    - name: advanced-cluster-management
      defaultChannel: release-2.8
      channels:
      - name: release-2.8
        minVersion: '2.8.6'
        maxVersion: '2.8.6'
      defaultChannel: release-2.9
      channels:
      - name: release-2.9
        minVersion: '2.9.4'
        maxVersion: '2.9.4'
    - name: multicluster-engine
      defaultChannel: stable-2.3
      channels:
      - name: stable-2.3
        minVersion: '2.3.6'
        maxVersion: '2.3.6'
      defaultChannel: stable-2.4
      channels:
      - name: stable-2.4
        minVersion: '2.4.5'
        maxVersion: '2.4.5'
```

2.  Kick off an oc-mirror

```
$ oc-mirror --config=config.yaml docker://mirror-dr.syangsao.net:8443/ocp4 --rebuild-catalogs
```    

oc-mirror will only mirror the most recent versions from the configuration:

ACM 2.9.4
MCE 2.4.5

This will then update the index on the destination repository which will only show this version being available.

Customer was on ACM v2.7 and needed to do a step upgrade.

ACM v2.7 -> v2.8 -> v2.9     

oc-mirror should be able to mirror multiple versions and also update the index file on the destination repository to have these versions available for OpenShift to see the available operator versions so the customer can upgrade accordingly, especially for step upgrades.    

$ oc-mirror version
