Add an option to disable parameter handler in composer production mode

[MartinLG]

When you use the composer post-install scripts to build your app in production, you don't always want your parameters to be handled by the parameter handler. We have the option to run composer with the --no-scripts flag, and create an other script to call after the composer install specifically in production, but it seems less comfortable than just add an option to disable the parameter handler when the --no-dev flag is given to composer.
