Pre install composer scripts

Hey,

We used in our current template pre-install-cmd and pre-update-cmd to enable Maintenance mode before starting the composer jobs.

The current composer-scripts in flex are hardbound to the post process.

My idea is now to add a new key to the config like pre-composer-scripts and post-composer-scripts (alias of composer-scripts to fix someday the name).

I would do also the implementation of this suggestion if its okay

Not sure this belongs to flex/composer. I personally don't deploy this way. This looks too specific to me.
