When the internal VIP is moved in the event of a failure of the active
controller, OpenStack services can become unresponsive as they try to
talk with MariaDB using connections from the SQLAlchemy pool.
It has been argued that OpenStack doesn't really need to use connection
pooling with MariaDB [1]. This commit reduces the use of connection
pooling via two configuration options:
- max_pool_size is set to 1 to allow only a single connection in the
pool (it is not possible to disable connection pooling entirely via
oslo.db, and max_pool_size = 0 means unlimited pool size)
- lower connection_recycle_time from the default of one hour to 10
seconds, which means the single connection in the pool will be
recreated regularly
These settings have shown better reactivity of the system in the event
of a failover.

This change adds support for encryption of communication between
OpenStack services and RabbitMQ. Server certificates are supported, but
currently client certificates are not.
The kolla-ansible certificates command has been updated to support
generating certificates for RabbitMQ for development and testing.
RabbitMQ TLS is enabled in the all-in-one source CI jobs, or when
The Zuul 'tls_enabled' variable is true.

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.

ironic dnsmasq is configured IPv4-only

KNOWN ISSUES (beyond us):
One cannot use IPv6 address to reference the image for docker like we
currently do, see: https://github.com/moby/moby/issues/39033
(docker_registry; docker API 400 - invalid reference format)
workaround: use hostname/FQDN
RabbitMQ may fail to bind to IPv6 if hostname resolves also to IPv4.
This is due to old RabbitMQ versions available in images.
IPv4 is preferred by default and may fail in the IPv6-only scenario.
This should be no problem in real life as IPv6-only is indeed IPv6-only.
Also, when new RabbitMQ (3.7.16/3.8+) makes it into images, this will
no longer be relevant as we supply all the necessary config.
See: https://github.com/rabbitmq/rabbitmq-server/pull/1982
For reliable runs, at least Ansible 2.8 is required (2.8.5 confirmed
to work well). Older Ansible versions are known to miss IPv6 addresses
in interface facts. This may affect redeploys, reconfigures and
upgrades which run after VIP address is assigned.
See: https://github.com/ansible/ansible/issues/63227
Bifrost Train does not support IPv6 deployments.

After all of the discussions we had on
"https://review.opendev.org/#/c/670626/2", I studied all projects that
have an "oslo_messaging" section. Afterwards, I applied the same method
that is already used in "oslo_messaging" section in Nova, Cinder, and
others. This guarantees that we have a consistent method to
enable/disable notifications across projects based on components (e.g.
Ceilometer) being enabled or disabled. Here follows the list of
components, and the respective changes I did.
* Aodh:
The section is declared, but it is not used. Therefore, it will
be removed in an upcomming PR.
* Congress:
The section is declared, but it is not used. Therefore, it will
be removed in an upcomming PR.
* Cinder:
It was already properly configured.
* Octavia:
The section is declared, but it is not used. Therefore, it will
be removed in an upcomming PR.
* Heat:
It was already using a similar scheme; I just modified it a little bit
to be the same as we have in all other components
* Ceilometer:
Ceilometer publishes some messages in the rabbitMQ. However, the
default driver is "messagingv2", and not ''(empty) as defined in Oslo;
these configurations are defined in ceilometer/publisher/messaging.py.
Therefore, we do not need to do anything for the
"oslo_messaging_notifications" section in Ceilometer
* Tacker:
It was already using a similar scheme; I just modified it a little bit
to be the same as we have in all other components
* Neutron:
It was already properly configured.
* Nova
It was already properly configured. However, we found another issue
with its configuration. Kolla-ansible does not configure nova
notifications as it should. If 'searchlight' is not installed (enabled)
the 'notification_format' should be 'unversioned'. The default is
'both'; so nova will send a notification to the queue
versioned_notifications; but that queue has no consumer when
'searchlight' is disabled. In our case, the queue got 511k messages.
The huge amount of "stuck" messages made the Rabbitmq cluster
unstable.
https://bugzilla.redhat.com/show_bug.cgi?id=1478274https://bugs.launchpad.net/ceilometer/+bug/1665449
* Nova_hyperv:
I added the same configurations as in Nova project.
* Vitrage
It was already using a similar scheme; I just modified it a little bit
to be the same as we have in all other components
* Searchlight
I created a mechanism similar to what we have in AODH, Cinder, Nova,
and others.
* Ironic

* Glance

* Trove

* Blazar

* Sahara

to be the same as we have in all other components
* Watcher
I created a mechanism similar to what we have in AODH, Cinder, Nova,
and others.
* Barbican
I created a mechanism similar to what we have in Cinder, Nova,
and others. I also added a configuration to 'keystone_notifications'
section. Barbican needs its own queue to capture events from Keystone.
Otherwise, it has an impact on Ceilometer and other systems that are
connected to the "notifications" default queue.
* Keystone
Keystone is the system that triggered this work with the discussions
that followed on https://review.opendev.org/#/c/670626/2. After a long
discussion, we agreed to apply the same approach that we have in Nova,
Cinder and other systems in Keystone. That is what we did. Moreover, we
introduce a new topic "barbican_notifications" when barbican is
enabled. We also removed the "variable" enable_cadf_notifications, as
it is obsolete, and the default in Keystone is CADF.
* Mistral:
It was hardcoded "noop" as the driver. However, that does not seem a
good practice. Instead, I applied the same standard of using the driver
and pushing to "notifications" queue if Ceilometer is enabled.
* Cyborg:
I created a mechanism similar to what we have in AODH, Cinder, Nova,
and others.
* Murano
It was already using a similar scheme; I just modified it a little bit
to be the same as we have in all other components
* Senlin

Due to poor planning on our variable names we have a situation where
we have "internal_address" which must be a VIP, but "external_address"
which should be a DNS name. Now with two vips "external_vip_address"
is a new variable.
This corrects that issue by deprecating kolla_internal_address and
replacing it with 4 nicely named variables.
kolla_internal_vip_address
kolla_internal_fqdn
kolla_external_vip_address
kolla_external_fqdn
The default behaviour will remain the same, and the way the variable
inheritance is setup the kolla_internal_address variable can still be
set in globals.yml and propogate out to these 4 new variables like it
normally would, but all reference to kolla_internal_address has been
completely removed.
