1. Proposed title of this feature request
    Allow to mirror specific openshift operator versions

2. What is the nature and description of the request?
    "oc-mirror" tool allows to mirror operators to a local registry and can filter the versions to mirror with the "maxVersion" and "minVersion" parameters but in practice, and due to the inherent complexity of the update graph of many operators, the "maxVersion" option needs to be set to the latest version at the risk of getting the well-known "multiple channel heads found in graph". This limits the flexibility of the mirroring process and also increases disk size and mirroring time in some cases.

3. Why does the customer need this? (List the business requirements here)
    Some customers doesn't need to mirror all available versions, they just need the specific version they are using, mirroring more versions just increases the storage and mirror time. Also this can work as another method to control the upgrade process of the operators.

4. List any affected packages or components.
