As a developer who has a handful of systems of various architectures at my disposal thanks to podman's remoting capabilities, I want to be able to use them to build a container image for multiple target platforms, much as I do today, albeit more slowly, using qemu-user-static.

We currently have support to build for multiple architectures using emulation but we want to be able to hand off per-architecture builds to remote podman services, and then transfer the newly-built images to the local system before adding them to a manifest list.

The POC card is https://issues.redhat.com/browse/RUN-1778

POC Implementation: https://github.com/nalind/buildfarm

This card implements the podman farm subcommand with the following subcommands implemented:

podman farm create

podman farm remove

podman farm update

podman farm list

Add docs and tests for these subcommands.
