1. Proposed title of this feature request
"oc-mirror" --v2” should mirror the images signature by default like "oc-mirror --v1"

2. What is the nature and description of the request?

By default "oc-mirror" --v2” does not mirror image signatures which is a default nature in "oc-mirror --v1".

https://docs.redhat.com/en/documentation/openshift_container_platform/4.19/html/disconnected_environments/mirroring-in-disconnected-environments#oc-mirror-signature-mirroring-procedure_about-installing-oc-mirror-v2

Signatures are required to be mirrored to initiate the upgrade otherwise the upgrade gets stuck with error
“The update cannot be verified”. Also, this is a prerequisite of the disconnected upgrade :

https://docs.redhat.com/en/documentation/openshift_container_platform/4.19/html/disconnected_environments/updating-a-cluster-in-a-disconnected-environment#update-disconnected_updating-disconnected-cluster

Something which is a must/prerequisite should be in default nature of "oc-mirror --v2" (like v1) and there should be no extra flag for this.

3. Why does the customer need this? (List the business requirements here)
The customers are more likely to make a mistake here by not mirroring the signatures due to missing extra flag "--remove-signatures=false" while mirroring images which will cause more upgrade issues. Even with "oc-mirror" v1, support gets many issues where the customers do not apply the signatures (even it is mirrored) and upgrades get stuck due to it.

4. List any affected packages or components.
