WIP: simplify helpers and implement resources for nodejs/ruby/go/composer

[alexAubin]

The problem

Redundant code in app packages, nodejs / ruby / go / composer should be managed declaratively like apt deps etc

Solution

Implement them as resource

PR Status

Kinda yolo, not complete

The code is kind of a mess because it needs to call bash commands with proper env vars x_x

[yalh76]

maybe the good time to switch nodejs from https://github.com/tj/n to https://github.com/nodenv/nodenv
as nodeenv, works like rbenv or goenv

There is also other *env available, can be seen as https://github.com/momo-lab/xxenv-latest
