Major Hayden 892c7fe46c Convert AIO bootstrap from bash to Ansible
This patch converts the AIO bootstrap process to use Ansible
instead of bash scripting. The patch also minimises the options
available to focus the role concerned to just handle an AIO
bootstrap, but gives it just enough flexibility to allow the
use of an external MongoDB database for Ceilometer/Aodh and
for a deployer to specify a secondary disk for the AIO to
consume.

A major change is that the AIO bootstrap process no longer
assumes that it can destroy a secondary boot device. It
requires a device name to be provided. This prevents horrible
surprises.

TODO (in subsequent patches):
 - update the developer AIO docs
 - convert run-playbooks.sh into an Ansible playbook

Implements: blueprint convert-aio-bootstrap-to-ansible
