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.

The Cinder API log is currently written to a file called
cinder-wsgi.log, and the WSGI logs to cinder-api.log. Fluentd
then tries to parse the WSGI log as an OpenStack log which
results in 'got incomplete line' errors and prevents proper
ingestion of these logs.

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.

The etcd service protocol is currently configured with internal_protocol.
The etcd service is not load balanced by a HAProxy container, so
there is no proxy layer to do TLS termination when internal_protocol
is configured to be "https".
Until the etcd service is configured to deploy with native TLS
termination, the etcd uses should be independent of
internal_protocol, and "http" by default.

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.
