Modularizatoin and parameters decoupling

To cover scenarios from All-In-One to multi controllers/nodes
- NonHA
- neutron

Same features scope as older NonHA monolitic version
but extending quickly...

Initially done with CI automation in mind, it simplifies
openstack's parameters complexity using Hiera yaml files.

Todo: Consolidate with HA

This is still Work in Progress:
Validating heat, cinder and compute nodes

Issues:
nova scheduler: miising SELinux AVC

Tested against RHOS5/RHEL7
