Add an option to skip composer install

[franzwilding]

It would be great to have an option to skip composer install, for example if you have all dependencies already in your git repo (which can be a good idea).

This would be awesome! I am currently running a static site on Netlify and all my PHP stuff on another Server. I do not need to install the php dependencies with composer on Netlify. A possibility to skip would be awesome!

+1 More control over the install phase would be an improvement.

Also, an option to customize composer args.

Agree with @nelson6e65 here. I'm trying to use the --no-dev argument with Netlify but can't figure out how to set it up.
