Convert vars in files to host_vars 
This change allows the MNAIO to really be used as a stand alone kick
system which has the potential to be developed into a stand alone
project. At the very least this change improves playbook performance
by scoping variables.

The inventory has been converted into a typical Ansible inventory and
the "servers" used in the MNAIO are now simply host_vars
which will trigger specific VM builds when instructed to do so. This
gives the MNAIO the ability to serve as a stand alone kick system which
could be used for physical hosts as well as MNAIO testing all through
the same basic set of playbooks. Should a deployer want to use this with
physical servers they'd need to do nothing more than define their basic
inventory and where the the required pieces of infrastructure needed to
PXE boot their machines.
