This allows for some real testing, especially in a multinode
environment.

In some resource-constrained environments, particularly during service
bootstrap Galera cluster nodes can experience timeouts in inter-node
communication.

This change sets the gmcast.peer_timeout based on the galera cluster
documentation:
https://galeracluster.com/library/documentation/galera-parameters.html

We are observing peer timeout issues on some CI runs - therefore raising
it to PT15S as in similar Ubuntu charms jobs.

There is no longer support for provisioning Ceph in Kolla Ansible, so we
should no longer say that it's only sometimes necessary to create the
cluster/pools/keyrings externally.

global_physnet_mtu needs to be set in neutron.conf, because linuxbridge-agent
discovers underlying vxlan0 interface mtu and returns an error when creating
vxlan port

CentOS8 job will not be added, because CentOS 8 iptables-ebtables package
is missing broute (--among-src) tables support required for linuxbridge agent,
see [1].

This makes it cleaner, allows reuse and outsourcing to zuul jobs
and enables us to create multiple of these overlay networks for
testing of more advanced scenarios.

Deprecates support for deploying with Hyper-V integrations.
In Victoria support for these will be removed from Kolla Ansible.

This is dictated by lack of interest and maintenance.

Currently we have a very wide /run mount for all Neutron/OVS services,
which allows sudo/rootwrap to contact with the hosts dbus - all symptoms
are documented in the related bug.

Since we use tcp connections to OVS from Neutron agents - removing
bind mounts.

Deprecates support for deploying with XenAPI integrations.
In Victoria support for these will be removed from Kolla Ansible.

This is dictated by lack of interest and maintenance, and upstream
decision of deprecation by Nova (for the same reasons).

The start-ovsdb-server script is only ever called with one argument by
kolla ansible, so we can remove the multiple argument handling used by
kolla-kubernetes (RIP).

This allows you to tune the performance of InfluxDB by locating the

Deprecates support for deploying MongoDB. In Victoria support for
deploying MongoDB will be removed from Kolla Ansible. Note CentOS 8
already lost support for MongoDB due to decisions made upstream.

This affects Panko as it will no longer be possible to get automatic
deployment of MongoDB database for it. However, the default, SQL,
backend is and will be supported via MariaDB.

MongoDB lost its position in OpenStack environment after
controversial relicensing under their custom SSPL (Server Side
Public License) which did not pass OSI (Open Source Initiative)
validation.

It looks like the only missing part was the actual mount of
/lib/modules

Now Cinder Backup volumes differ from Cinder Volume volumes only
by /etc/target which is not relevant (Cinder Backup does not
provide a target).

while running kolla-ansible, so need to skip it.
