add support for composer global plugins

[rafaeltuelho]

Some applications rely on composer plugins to properly install their dependencies. For example, some applications delegates to composer the installations of npm and bower packages. Composer uses the plugin fxpio/composer-asset-plugin for this kind of 3rd party deps management. The issue is fxpio/composer-asset-plugin only can be installed/enable globally. So the image should install install using the command:

composer global require "fxp/composer-asset-plugin:~1.3"

I managed to workaround this "limitation" by copying the original s2i assemble script and embedding it inside my app src (.s2i/bin/assemble). See the customized version here: https://gist.github.com/rafaeltuelho/628da4576ec9f34c6c28cd9e5b909ef0#file-customized_php_s2i_assemble-sh-L46-L51

@remicollet Could you please tak a look if it makes sense to use fxpio/composer-asset-plugin by default in our assemble script? Also what do you think about #166 which relates also to composer?

I don't think it make sense, we obviously cannot install everything
and this project seems inactive (last release in 2019, 4 years ago)
