basic ansible setup.
Run keystone and glance.
Add db_sync task
Add default keystone users/tenants.
Fully configure keystone and glance:

- populate keystone users/roles/services
- genrate keystone ssl
- fix yaml so all clients install
Nova api works.
Run nova-compute service.
Run nova compute and quantum:

- run nova compute service
- run all quantum services on respective nodes
- use review.openstack.org git remote instead of github.
- use pypi.openstack.org mirror instead of pypi.
Run horizon.
Add defualt quantum subnet.
Add a script which boots nova vms for testing.
Add install script for osx.
Install fireball dependencies on osx.
Add name to python deps task.
Massive refactoring:

- Introduce the concept of multiple 'envs'
- Move all vars to be group vars instead of global
- Handle quantum -> neutron rename
- Organize tasks and templates into individual directories.
Update notes.
Replace references to quantumclient with neutronclient:

quantumclient is no more, so fork ansible stdlib's
quantum_network and quantum_subnet modules to this repo,
and gsub s/quantum/neutron/.

These can go away once upstream ansible supports neutron.
Configure ovs bridges for quantum.
Fix horizon's restart-apache handler.
Install antsy gem, for use in custom ansible ruby modules.
