RFE: Allow filtering containers by command

[krystalcode]

Feature request description

I want to bulk remove any intermediate containers left by Buildah. I understand that these are listed by podman ps --external and they are the ones that have "buildah" as the Command. Currently, podman ps --filter command=buildah raises an invalid filter error.

Suggest potential solution

Add a command filter so that I can run podman ps --external --filter command=buildah --format "{{.ID}}" | xargs podman rm.

Have you considered any alternatives?

thanks for opening the issue, it seems like a good candidate for "Good First Issue".

The main difficulty in the implementation is to apply the filters to the external containers, which we don't currently do.

Hello @giuseppe,

I decided to implement filtering of commands to all kind of containers storage: external and for podman, I guess, this approach is better than just implementing this feature for only one sort of storage.
If you don't want to accept this approach then I will put it away and implement filtering for external container storage only.

Thank you.
