A combination of durable queues and classic queue mirroring can be used
to provide high availability of RabbitMQ. However, these options should
only be used together, otherwise the system will become unstable. Using
the flag ``om_enable_rabbitmq_high_availability`` will either enable
both options at once, or neither of them.
There are some queues that should not be mirrored:
* ``reply`` queues (these have a single consumer and TTL policy)
* ``fanout`` queues (these have a TTL policy)
* ``amq`` queues (these are auto-delete queues, with a single consumer)
An exclusionary pattern is used in the classic mirroring policy. This
pattern is ``^(?!(amq\\.)|(.*_fanout_)|(reply_)).*``

When running in check mode, some prechecks previously failed because
they use the command module which is silently not run in check mode.
Other prechecks were not running correctly in check mode due to e.g.
looking for a string in empty command output or not querying which
containers are running.
This change fixes these issues.

Regularly, we experience issues in Kolla Ansible deployments because we
use wrong options in OpenStack configuration files. This is because
OpenStack services ignore unknown options. We also need to keep on top
of deprecated options that may be removed in the future. Integrating
oslo-config-validator into Kolla Ansible will greatly help.
Adds a shared role to run oslo-config-validator on each service. Takes
into account that services have multiple containers, and these may also
use multiple config files. Service roles are extended to use this shared
role. Executed with the new command ``kolla-ansible validate-config``.

A system-scoped token implies the user has authorization to act on the
deployment system. These tokens are useful for interacting with
resources that affect the deployment as a whole, or exposes resources
that may otherwise violate project or domain isolation.
Since Queens, the keystone-manage bootstrap command assigns the admin
role to the admin user with system scope, as well as in the admin
project. This patch transitions the Keystone admin user from
authenticating using project scoped tokens to system scoped tokens.
This is a necessary step towards being able to enable the updated oslo
policies in services that allow finer grained access to system-level
resources and APIs.

service policies is:

By default, Ansible injects a variable for every fact, prefixed with
ansible_. This can result in a large number of variables for each host,
which at scale can incur a performance penalty. Ansible provides a
configuration option [0] that can be set to False to prevent this
injection of facts. In this case, facts should be referenced via
ansible_facts.<fact>.
This change updates all references to Ansible facts within Kolla Ansible
from using individual fact variables to using the items in the
ansible_facts dictionary. This allows users to disable fact variable
injection in their Ansible configuration, which may provide some
performance improvement.
This change disables fact variable injection in the ansible
configuration used in CI, to catch any attempts to use the injected
variables.

There are a few issues fixed here:
- The Barbican API service doesn't set a log file, so all the Barbican API
service logs go to loadwsgi.py.log by default.
- The logs in loadwsgi.py.log are not ingested properly by Fluentd.
- uWSGI logs go to barbican-api.log. This would normally be used as the log
file for the Barbican API service logs.
This patch makes the following changes to address the above issues:
- All uWSGI logs (from the Emperor and Vassals) go to barbican_api_uwsgi_access.log
Although these logs aren't strictly all access logs, this follows the existing
pattern for WSGI logs.
- The Barbican API service logs are written to barbican-api.log instead of
loadwsgi.py.log. This follows the pattern used by other OpenStack services.
- Fluentd is configured to parse the Barbican API service logs as it would with
other OpenStack Python services.

Including tasks has a performance penalty when compared with importing
tasks. If the include has a condition associated with it, then the
overhead of the include may be lower than the overhead of skipping all
imported tasks. In the case of the register.yml and bootstrap.yml
includes, all of the tasks in the included file use run_once: True.
The run_once flag improves performance at scale drastically, so
importing these tasks unconditionally will have a lower overhead than a
conditional include task. It therefore makes sense to switch to use
import_tasks there.
See [1] for benchmarks of run_once.

The goal for this push request is to normalize the construction and use
of internal, external, and admin URLs. While extending Kolla-ansible
to enable a more flexible method to manage external URLs, we noticed
that the same URL was constructed multiple times in different parts
of the code. This can make it difficult for people that want to work
with these URLs and create inconsistencies in a large code base with
time. Therefore, we are proposing here the use of
"single Kolla-ansible variable" per endpoint URL, which facilitates
for people that are interested in overriding/extending these URLs.
As an example, we extended Kolla-ansible to facilitate the "override"
of public (external) URLs with the following standard
"<component/serviceName>.<companyBaseUrl>".
Therefore, the "NAT/redirect" in the SSL termination system (HAproxy,
HTTPD or some other) is done via the service name, and not by the port.
This allows operators to easily and automatically create more friendly
URL names. To develop this feature, we first applied this patch that
we are sending now to the community. We did that to reduce the surface
of changes in Kolla-ansible.
Another example is the integration of Kolla-ansible and Consul, which
we also implemented internally, and also requires URLs changes.
Therefore, this PR is essential to reduce code duplicity, and to
facility users/developers to work/customize the services URLs.

correctness we should fix the condition to reference the host OS rather
than the container OS, since that is where the /etc/timezone file is
located.

Including tasks has a performance penalty when compared with importing
tasks. If the include has a condition associated with it, then the
overhead of the include may be lower than the overhead of skipping all
imported tasks. In the case of the check-containers.yml include, the
included file only has a single task, so the overhead of skipping this
task will not be greater than the overhead of the task import. It
therefore makes sense to switch to use import_tasks there.

The common role was previously added as a dependency to all other roles.
It would set a fact after running on a host to avoid running twice. This
had the nice effect that deploying any service would automatically pull
in the common services for that host. When using tags, any services with
matching tags would also run the common role. This could be both
surprising and sometimes useful.
When using Ansible at large scale, there is a penalty associated with
executing a task against a large number of hosts, even if it is skipped.
The common role introduces some overhead, just in determining that it
has already run.
This change extracts the common role into a separate play, and removes
the dependency on it from all other roles. New groups have been added
for cron, fluentd, and kolla-toolbox, similar to other services. This
changes the behaviour in the following ways:
* The common role is now run for all hosts at the beginning, rather than
prior to their first enabled service
* Hosts must be in the necessary group for each of the common services
in order to have that service deployed. This is mostly to avoid
deploying on localhost or the deployment host
* If tags are specified for another service e.g. nova, the common role
will *not* automatically run for matching hosts. The common tag must
be specified explicitly
The last of these is probably the largest behaviour change. While it
would be possible to determine which hosts should automatically run the
common role, it would be quite complex, and would introduce some
overhead that would probably negate the benefit of splitting out the
common role.
