This reverts commit 9cae59be.

Reason for revert: This patch was found to introduce issues with fluentd customisation. The underlying issue is not currently fully understood, but could be a sign of other obscure issues.

Closes-Bug: #1906288

Main plays are action-redirect-stubs, ideal for import_tasks.

This avoids 'include' penalty and makes logs/ara look nicer.

Fixes haproxy and rabbitmq not to check the host group as well.

Implements: blueprint migrate-to-ansible-2-2-0

Certain services such as Murano and trove require access to a rabbitmq
instance from tenant networks. [0]

Exposing the internal rabbitmq to end users is a security hole, hence
there are two options, 1) use vhosts in the existing rabbitmq, or two a
separate rabbitmq instances. Given the importance of rabbitmq to the
OpenStack deployment, we have decided to go with a separate instance.
Refer to [1] for more detail on the various options.

This change makes the rabbitmq role generic so that it can be reused, in
this case to start 'outward_rabbitmq'. It needs to be exposed via
haproxy both for network isolation and also because this is what Murano
configuration requires.

Follow on patches will be added to add a vhost in this outward instance
for Murano and other services which require access.

Stagger the start times of the rabbitmq daemon so rabbitmq neither
crashes and also properly forms a cluster.  This problem exists in
the latest rabbitmq 3.5.4 available on rabbitmq.com for download.

The original purpose for having an abstract like 'database' rather than
the service name of 'mariadb' has been change. Our direction is different
and this patch reflects consistent naming throughout

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.

Implements the initial structure for variable substitution in ansible.

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.
