From 88f8d96ed8e7edcb4dfdb3de707034036bab27ff Mon Sep 17 00:00:00 2001

Subject: Add support for --platform

For docker compatibility we need to support --platform
flag.

podman create --platform
podman run --platform
podman pull --platform

Since we have --override-os and --override-arch already
this can be done just by modifying the client to split
the --platform call into os and arch and then pass those
options to the server side.

Fixes: https://github.com/containers/podman/issues/6244
