podman-compose extension for --pod-args

[TheMDev]

The recent PR https://github.com/containers/podman-compose/pull/964 implemented the ability to set --in-pod in the compose file. However, there still does not appear to be a way to set --pod-args in the compose file. This would be pretty useful as it would allow for options such as --infra, --infra-command, --infra-image, --infra-name, --share and more to be set in the compose file instead of needing to pass them in with --pod-args.

Compose example:

x-podman:
    in_pod: true
    pod_args: '--infra=true --infra-name=pod_unipi_infra --share=""'

Possible partial implementation:
