Subject: Generate systemd unit files for containers

the podman generate systemd command will generate a systemd unit file
based on the attributes of an existing container and user inputs.  the
command outputs the unit file to stdout for the user to copy or
redirect.  it is enabled for the remote client as well.

users can set a restart policy as well as define a stop timeout
override for the container.
