Feature request description

The --replace option gives users a quick way to create an object without having to do a racy check if the object exists and then removing it, when it wants to create a new object.

Suggest potential solution

Add --replace option to artifact add, which will remove the artifact if it exists before creating it.

Have you considered any alternatives?

Yes checking if it exists and removing it.

Additional context

podman container create --replace exists and is a handy option. podman build will automatically create an new image even if the existing image already existed.
