This makes some changes to init-runonce to allow using Ansible as well as
updating it to use the openstack-client where applicable since the
keystone-client is not usable with keystone v3 api at all.

The ml2_conf.ini file which sets OpenVswitch as the mechanism driver
was not being copied to the corect place.  This patch resolves that
problem.

The neutron-agents l3 agent requires access to the OVS database via
access to /run.  It also needs to have ovs-vsctl binary available in
the container.

Ansible will exec a script in the OVS container to ensure the bridge and

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.

The commands used to create a temporary file on the localhost were
vulnerable to a symlink attack. Removing the shell module and ensuring
the ansible copy and file module is used will verify this file exists as a

Due to the licensing issues and the modules not existing in upstream
Ansible yet, I have written a simple module to fill the gaps.

This also uses Keystone v2.0 for all create of users, roles and
endpoints. The implementation of Keystone v3 must be discussed after the
new modules arrive.

This ansible module for docker-compose allows for idempotency. I have
submitted a pull request upstream to ansible-modules-extra to include
this new module. When/if the module is accepted upstream if can be
removed from the local module library.

The two playbooks have been updated to use this module. The database
data container does not support idempotency due to the fact that it
exists instead of sleeps. Therefore each time `docker-compose up` is
called, it will start the container and register a change. The
message-broker does not have this issue and will remain unchanged even
repeatedly running these playbooks.

Due to the use of a special branch of docker-compose provided by sdake,
this module requires at least docker-compose==1.2.0rc1

This adds a very basic structure to begin supporting ansible in Kolla.
Ansible can support complete idempotency, but wrapping docker-compose
does not allow idempotency at this time. These playbooks will be
extended to compensate for that in future patches.
