Title: Fix: Allow webRunner to be overridden by users with config files

Command line arguments trump all other configuration. This means if we set default options in the option parser it's impossible for the user to override with other configuration styles (env, config file, etc). We shouldn't set defaults here and if we want to display the defaults we should do it another way probably.
