Implements: blueprint heat-fig-update

Fig is initially being evaluated to provide container set
functionality. Therefore, the heat template needs to be updated
to support running fig on Kolla nodes. This patch adds the
required directories, files, and commands to run fig and a
RabbitMQ container for testing.
