This change ensures that all handlers that are triggered are fired which
should assist in cases where a playbook fails and is then rerun.

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.

Sadly the log node does not have enough ram to run a full ansible run.
Ansible 2.x requires more ram than one would expect, especially when the
inventory gets large. this change moves the deploy node to infra1 as it
will already have the ram needed to run the playbooks. Additionally the
container storage for infra nodes was too small which forces builds into
error. The default storage for VMs has been set to 90GiB each and the
preseed will create a logical volume for VMs mounted at /var/lib/lxc.
While the limited ram works well for the VMs and within a running
deployment of OSA, ansible-playbook is subject to crash like so:
An exception occurred during task execution. To see the full traceback,
use -vvv. The error was: OSError: [Errno 12] Cannot allocate memory
fatal: [infra1_cinder_api_container-b38b47ea]: FAILED! =>
{"failed": true, "msg": "Unexpected failure during module execution.", "stdout": ""}
So infra nodes have had the memory constraint raised to 8GiB

This change ensures that the VMs and host systems cache apt packges
locally which will speed up the boot and deployment process.

This reduces the resource consumption by removing the deploy node and
using the log node instead. This also ups the ram allocation to the
infra hosts which will improve the deployment experience by ensuring we
don't run out of memory.

The original mnaio was built using a lot of bash and was tailored
specifically for ubuntu 14.04. The new mnaio was built using a mix of
bash and ansible and was tailored specifically for ubuntu 16.04. This
patch takes the two code bases and combines the best things from each
method and wraps it up into a single code path all written using ansible
playbooks and basic variables.
While underlying system has changed the bash environment variable syntax
for overrides remains the same. This allows users to continue with what
has become their normal work-flow while leveraging the new structure and
capabilities.
High level overview:
* The general performance of the VMs running within the MNAIO will now
be a lot better. Before the VMs were built within QCOW2 containers,
while this was flexible and portable it was slower. The new
capabilities will use RAW logical volumes and native IO.
* New repo management starts with preseeds and allows the user to pin
to specific repositories without having to worry about flipping them
post build.
* CPU overhead will be a lot less. The old VM system used an
un-reasonable number of processors per VM which directly translated
to sockets. The new system will use cores and a single socket
allowing for generally better VM performance with a lot less
overhead and resource contention on the host.
* Memory consumption has been greatly reduced. Each VM is now
following the memory restrictions we'd find in the gate, as a MAX.
Most of the VMs are using 1 - 2 GiB of RAM which should be more than
enough for our purposes.
Overall the deployment process is simpler and more flexible and will
work on both trusty and xenial out of the box with the hope to bring
centos7 and suse into the fold some time in the future.

More values have been added to the variables.sh file. None of these have
been adjusted from the default values but this now provides a standard

files.
