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 Zun configuration file does not set the CA for the clients the Zun
service uses: zun_client, glance_client, neutron_client, cinder_client,
and placement_client. This will cause the Zun service to fail when
TLS is enabled in the OpenStack deployment.

Zun has a new component "zun-cni-daemon" which should be
deployed in every compute nodes. It is basically an implementation
of CNI (Container Network Interface) that performs the neutron
port binding.
If users is using the capsule (pod) API, the recommended deployment
option is using "cri" as capsule driver. This is basically to use
a CRI runtime (i.e. CRI plugin for containerd) for supporting
capsules (pods). A CRI runtime needs a CNI plugin which is what
the "zun-cni-daemon" provides.
The configuration is based on the Zun installation guide [1].
It consits of the following steps:
* Configure the containerd daemon in the host. The "zun-compute"
container will use grpc to communicate with this service.
* Install the "zun-cni" binary at host. The containerd process
will invoke this binary to call the CNI plugin.
* Run a "zun-cni-daemon" container. The "zun-cni" binary will
communicate with this container via HTTP.

Per [1] Docker uses API version 1.26 since daemon version 1.13.1.
Kolla Ansible forced a limit on the Docker API version reported
to Zun of 1.24 which was surprising users and preventing
usage of Docker runtime selection via Zun.
The default of Zun is 1.26 [2] which enables runtime selection.
Zun does not use this parameter for anything else atm.

ml2 for xenapi
Xen is not supported too well.
This would require working with XenAPI facts.
rp_filter setting
This would require meddling with ip6tables (there is no sysctl param).
By default nothing is dropped.
Unlikely we really need it.
ironic dnsmasq is configured IPv4-only
dnsmasq needs DHCPv6 options and testing in vivo.
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 the integration with placement [1], we need to configure how
zun-compute is going to work with nova-compute.
* If zun-compute and nova-compute run on the same compute node,
we need to set 'host_shared_with_nova' as true so that Zun
will use the resource provider (compute node) created by nova.
In this mode, containers and VMs could claim allocations against
the same resource provider.
* If zun-compute runs on a node without nova-compute, no extra
configuration is needed. By default, each zun-compute will create
a resource provider in placement to represent the compute node
it manages.
