Throughout the project overtime some of these file permissions have
changed to have an executable bit. They should not have this bit set.

Ansible installation of rsyslog container

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.

Partially-implements: blueprint ansible-service

Adds initial support for Rabbitmq in Ansible using the CONFIG_EXTERNAL methods.

Additionally, this refactors some of the Rabbitmq config script to allow for
reuse by CONFIG_EXTERNAL.

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.
