Finish runner --help outputs with unattended config doc

[TingluoHuang]

./config.sh/cmd --help will only print out some basic info about how to use the cli.

Ex:

H:\Source\runner_new\_layout>config.cmd --help

Commands:,
 .\config.cmd          Configures the runner
 .\config.cmd remove   Unconfigures the runner
 .\run.cmd             Runs the runner interactively. Does not require any options.

Options:
 --version  Prints the runner version
 --commit   Prints the runner commit
 --help     Prints the help for each command

We should include more information in this help output, like all arguments the runner takes durring config and example for doing unattended runner config.
