Add --remote option

[thomas-huegel]

Is your feature request related to a problem? Please describe. I would like to use podman-compose against a remote server.

Describe the solution you'd like I would like to be able to put a --remote option on the command line. It would be forwarded to the underlying podman command.

Thanks!

The feature would be really appreciated, both for Windows users who use VMs and Linux users who run podman under a rootless user account.

The separate but related issue is that --remote option is (most probably) silently ignored. I tried using compose with --remote flag and instead of failing it created containers under my account without any warnings.

You can set the environment variable CONTAINER_HOST=ssh... or unix... and then podman runs in remote mode whith this host by default, without the flag, and compose works too

podman-compose systemd --action register does not seem to work remotely with CONTAINER_HOST.
