Libvirt shuts down existing virtual machines.  To solve this problem,
the /var/lib/libvirt directory needs to be persisted.  By persisting
this directory in the nova data container, libvirt can communicate
with the sockets setup by the previous data container.

Make nova-libvirt and nova-compute use a data container called
nova_data.  This data container contains /var/lib/nova/instances
data so upgrades to nova-compute work properly.

Currently bootstrap containers are waited to exit but are not
checked for exit status and ansible runs further tasks. If
bootstrapping fails we notice it at much later time.

Nova-compute is curerntly generating a backtrace when trying to nova
boot a VM.  The backtrace is described in the bug log.  Bind-mounting
/sys/fs/cgroup:/sys/fs/cgroup in the libvirt container resolves the
problem.

The register operation was registering user_database which is a global
variable in group_vars/all.yml.  This results in glance not being deployable
because user_database is overwrriten at keystone task registration time.

The result of this is the playbooks fail to deploy.

Currently we require a slew of deps on each destination node, this
includes a gcc compiler and installing things via pip. We can remove
these dependencies by containerizing them and running and Ansible
inside the container itself. The container would then report back
facts about idempotency.

Libvirt requires pid_mode to Host to operate on Fedora Hosts.  Further
we will need this for libvirt upgrade.  I am not entirely sure why
libvirt running with pid=host gets things working, but it definately
has something to do with CentOS's libvirt's integration with systemd.

Nailing down the problem, the interface to the Docker module accepts only
None or "host".  There is no way to generate a None type except with !!null
in yml, but this does not work in the jinja2 parser.  As a result, one
solution is this conditional.  A better long term solution would be for
the Docker module to take some other argument to indicate None that can
be expressed in a string.
