Add a field to `RemoveImages` that would ingore if a specified image
does not exist and not throw an error.
The intended use case is adding a `podman rmi --ignore` flag.

When removing an image by name, do not remove the image and all its
tags, even if force is set. Instead, just untag the specified name.
Note: adjust the load test to preserve the order in the untagged field.
Also vendor in the latest HEAD in containers/image to fix a bug revealed
in Podman CI.
