Description of problem:
Currenlty product is packaged using add-ons approach to product layering on top of EAP. Since we want JPP to have it's own product identity add-ons approach is not appropriate.

Version-Release number of selected component (if applicable):
ER05

How reproducible:
n/a

Steps to Reproduce:
n/a

Actual results:
- There's modules/system/add-ons/gatein directory containing gatein modules
- There's no modules/layers.conf file
- Some content is added to and some removed from modules/system/layers/base
- Modules root ordering goes like this:
1) modules
2) modules/system/layers/base
3) modules/system/layers/add-ons/gatein


Expected results:
- There's modules/system/layers/gatein directory containing gatein modules
- There is modules/layers.conf file containing a line: 'layers=gatein'
- modules/system/layers/base is untouched, left unchanged
- Modules root ordering goes like this:
1) modules
2) modules/system/layers/gatein
3) modules/system/layers/base

Additional info:
The new approach will affect modules root ordering. But since we don't have any modules with same ids in gatein, we aren't overwriting any EAP provided modules.
