Render {{ openstack_service_workers }} for workers
of each openstack service is not enough. There are
several services which has to have more workers because
there are more requests sent to them.
This patch is just adding default value for workers for
each service and sets {{ openstack_service_workers }} as
default, so value can be overrided in hostvars per server.
Nothing changed for normal user.

I've used the values from the endpoint. This was mostly a straight
forward copy and paste, except:
- versioned endpoints e.g cinderv3 where I stripped the version
- monasca has multiple endpoints associated with a single service. For
this, I concatenated logging and monitoring to be logging-monitoring.

In services which use the Apache HTTP server to service HTTP requests,
there exists a TimeOut directive [1] which defaults to 60 seconds. APIs
which come under heavy load, such as Cinder, can sometimes exceed this
which results in a HTTP 504 Gateway timeout, or similar. However, the
request can still be serviced without error. For example, if Nova calls
the Cinder API to detach a volume, and this operation takes longer
than the shortest of the two timeouts, Nova will emit a stack trace
with a 504 Gateway timeout. At some time later, the request to detach
the volume will succeed. The Nova and Cinder DBs then become
out-of-sync with each other, and frequently DB surgery is required.
Although strictly this category of bugs should be fixed in OpenStack
services, it is not realistic to expect this to happen in the short
term. Therefore, this change makes it easier to set the Apache HTTP
timeout via a new variable.
An example of a related bug is here:
https://bugs.launchpad.net/nova/+bug/1888665
Whilst this timeout can currently be set by overriding the WSGI
config for individual services, this change makes it much easier.

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.

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.

(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.

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.

* Nova_hyperv:

* Vitrage

* Sahara
It was already using a similar scheme; I just modified it a little bit

* 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

be removed in an upcomming PR.

Heat has a new option (server_keystone_endpoint_type), which can be used
to set the keystone endpoint used by instances to make callbacks to
heat. This needs to be public, since we can't assume users have access
to the internal API. However, the current method of setting
[clients_heat] endpoint_type means that communication from heat to its
own API (e.g. when a stack is a resource in another stack) uses the
public network also, and this might not work if TLS is enabled.
This change uses server_keystone_endpoint_type to keep instance traffic
on the public API, and removes the [clients_heat] endpoint_type option
to use the default in [clients] endpoint_type of internalURL.
This feature was added to heat in https://review.opendev.org/#/c/650967.

This allows heat service endpoints to use custom hostnames, and adds the
following variables:
* heat_internal_fqdn
* heat_external_fqdn
* heat_cfn_internal_fqdn
* heat_cfn_external_fqdn
These default to the old values of kolla_internal_fqdn or
kolla_external_fqdn.
This also adds heat_api_listen_port and heat_api_cfn_listen_port
options, which default to heat_api_port and heat_api_cfn_port for
backward compatibility.
These options allow the user to differentiate between the port the
service listens on, and the port the service is reachable on. This is
useful for external load balancers which live on the same host as the
service itself.
