In order to improve the readability and robustness of the mnaio feature
I have replaced the shell out to virsh tasks to use the virt module
where available. I have also created a vm-status play that will
hopefully help resolve SSH failures into the VMs. This play utilizes
the block/rescue/handler pattern to attempt to restart the VM once if
it fails the initial SSH check. Hopefully this will reduce the SSH
failures due to a suck VM. This adds a new variable called
vm_ssh_timeout which allows the deployer an easy place to override the
default timeout. The python-lxml package is needed for the virt module.

mnaio uses LVM as default VM disk backend but that
requires a lot of available disk space.
A alternative option, the qcow2 file based backend
is added to take benefit of thin provisioning.
This backend can be triggered by setting the override
`default_vm_disk_mode` to `file`

This allows the setting of an ansible osa_disable_serial variable
that drops in a config to set all of the serial settings to 100%
to disable throttling. The exception being keystone as it has a
race condition that prevents it. The default is 'false' and can
be set in the MNAIO_ANSIBLE_PARAMETERS var before running the
build.sh script.

This change updates the preseed files and the default
openstack-user-config file so that deployers can use and test nspawn
type containers using the in-built automation.

Adds support for iPXE scripting. Allows for the
operator to specify a remote iPXE kernel to pull in
newer iPXE kernel features and specify a remote
default iPXE script for customizing the multi node
for other types of deployments.
Switches the installations to use netboot installer kernels
instead of ISO retrival and extraction.
Restructures directory to allow for future multi node configs
instead of just debian based installs.

This change makes it possible to deploy ACNG within a physical
host NOT automatically tied to an MNAIO installation. This also
adds an infra preseed file which can be used to provision physical
hosts.
By default the domain name is now passed into the server boot params
which is useful when setting up an environment in support of
RFC-1034/5.
Ubuntu 16.04 has an issue with the options "quiet splash" being passed
in which cause it to have no usable console. See [Related-Issue] for
more.

Deployers sometime need the ability to opt out of specific deployment
groups. While a deployer can modify or extend the configuration
groups using conf.d files, until now they didn't have the ability
to remove groups when testing different scenarios. This change
simply adds conditionals to the openstack_user_config giving users
the ability to tailor the default user configuration options to
their needs.

* added ip alias for interfaces
* Update settings and improve vm performance
* Change the VG name in VMs. The VG name was changed so that the volume
which is being used by VMs can be mounted on a physical host, and not
conflict, with standard volume group naming. This is usful when a VM
is DOA and a deployer wants to disect the instance.

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.
