Proposed title of this feature request

There should be some option with oc-mirror command, so when the oc-mirror command the operator and catalog images should be pushed in different repositories.

 List any affected packages or components.

Currently when we run oc-mirror the catalog image will get push in <Registry-url:port>/devworkspace/redhat/redhat-operator-index:v4.12 repository and operator image in this <Registry-url:port>/devworkspace/openshift4 repository.

excepted behavior is:

The images should get in different repositories not in same as we can see in above example.  The both the images are pushing in same parent directory which is devworkspace.
