Chris Webb 0310c5726f main: Show help text when run without arguments 
cloud-hypervisor, ch-remote, vhost-user-block and vhost-user-net all
need at least one argument to do anything useful, so printing command
help is helpful when they are run without arguments or a subcommand.

Use clap::Command::arg_required_else_help(true) to do this.
