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.
Run now takes a context as well as a statebag. We'll assign the context
to the blank identifier to prevent namespace collisions. We'll let the
step authors opt-in to using the context.
`find . -iname "step_*.go" -exec gsed -i'' 's/func \(.*\)Run(/func \1Run(_ context.Context, /' {} \;`
