Fix resize race with podman exec -it
When starting a process with `podman exec -it` the terminal is resized after the process is started. To fix this allow exec start to accept the terminal height and width as parameter and let it resize right before the process is started. Fixes #10560 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
