Openstack ansible manifest

[Miroslav Suchý]

Following yesterday meeting:
This is may work-in-progress of openstack ansible manifest:
https://github.com/xsuchy/openstack-ansible-install

I decided to skip all this undercloud etc. and just follow what main wiki suggest:
http://docs.openstack.org/trunk/install-guide/install/yum/content/index.html

Far from being finished, but comments and collaborators are welcome.
