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.

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.

neutron-server was not properly using ml2_conf.ini

nova did not have ovs utils, and it had incorrect libvirt permissions

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.
