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.
Install custom horizon images.
Use roles in compute playbook.
Update todo list to reflect latest work.
Add custom horizon images.
Use roles in controller playbook instead of tasks.
Run db sync task whenever db/main is run.

This was impossible until keystone-manage, nova-manage etc.
were installed before db, which happened with recent change to
use roles in the controller playbook.
Flush handlers in keystone, so that pip install happens immediately.
Fix typo in nova handlers: s/pypy/pypi/
Add trailing space in nova template param - it was ugly. :)
Tweak config to use kvm and non-https pypi.

- Using https://pypi.openstack.org seems to be broken at the moment.

- KVM is faster than qemu, but requires hardware support, and cannot
  be run nested, in most cases.
Flush handlers before running db-sync:

so that keystone-manage, nova-manage, etc. are installed.
Install NoVNC and nova-novncproxy.
Add a skeleton for new deployment doc.
Begin document hardware provisioning step.
Update docs.
