quadlet kube should use logging

[alexlarsson]

quadlet uses --log-driver passthrough for regular .container files. This means just forwarding the journal socket to the container as-is. This has the advantage that journald can see who the actual sender of the log event is, rather than thinking everything comes from the conmon process. It also means conmon doesn't have to copy all the log data.

I think we should do the same for .kube files, and thankfully the kube play already has a commandline option for this.

@alexlarsson I think we can exploit the --service-container flag a bit. It's an internal flag and hidden from the CLI, and only used in the context of running in systemd.

Hence, such defaults can be set automatically with --service-container. For sure, it doesn't hurt to set them explicitly.

Working on this issue. While the change is simple, since setting the log-driver to passthrough is not allowed on TTY, this change breaks the test for --service-container.
