By default the Google builder will wrap any provided startup script file in order to track its execution via custom metadata. The wrapper script can add a bit of complexity to the start script file so a new option is being added `wrap_startup_script`. This option allows a user to disable the script wrapping and just let GCE do its own thing when executing a startup script.
