Uniform initialization methods

For the moment, the components/plugins have implicit initialization methods.

Amongst them:

• They read directly from env variables
• They read from CFG
• The have parameters at__init__

We should refactor it so that each component/plugin takes explicitly the necessary parameters from the __init__ method. Then, the top-level function superduper() should be responsible for setting the appropriate parameters.
