Missing --remove-signatures in `podman-remote push`

[cfergeau]

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

podman-remote push does not support --remove-signatures

Steps to reproduce the issue:

These commands are run on macOS, so this is using podman-remote

1. podman pull registry.access.redhat.com/ubi8

2. podman push registry.access.redhat.com/ubi8 quay.io/teuf/ubi8

Describe the results you received:

This fails with Error: Copying this image would require changing layer representation, which we cannot do: "Would invalidate signatures"

Describe the results you expected:

On linux, I can use podman push --remove-signatures to avoid this (maybe there are other ways to deal with it, but I'm not aware of them). On macOS, I don't have such an option.

Have you tested with the latest version of Podman and have you checked the Podman Troubleshooting Guide? (https://github.com/containers/podman/blob/main/troubleshooting.md)

I tested latest version, I also looked at a git build where I could not find the option.
