The CentOS Stream 8 section used the wrong heading style, which broke
the rest of the document, making the other headings the wrong sizes.

By default, Ansible injects a variable for every fact, prefixed with
ansible_. This can result in a large number of variables for each host,
which at scale can incur a performance penalty. Ansible provides a
configuration option [0] that can be set to False to prevent this
injection of facts. In this case, facts should be referenced via
ansible_facts.<fact>.

This change updates all references to Ansible facts within Kayobe
from using individual fact variables to using the items in the
ansible_facts dictionary. This allows users to disable fact variable
injection in their Ansible configuration, which may provide some
performance improvement.

This change disables fact variable injection in the ansible
configuration used in CI, to catch any attempts to use the injected
variables.

If no public API network is used, as in the case of typical all-in-one
environments, the checks in kolla-ansible.yml, task "Validate Kolla
Ansible API address configuration" may fail. This happens only when
using the new kolla_internal_vip_address variable, and not if the legacy
vip_address network attribute is used.

This change fixes the issue by only checking for valid external VIP
address/FQDN configuration when a separate public API network is in use.
If the external VIP/FQDN are not set, then Kayobe no longer defaults
their values to the internal VIP/FQDN, instead relying on the Kolla
Ansible defaults to do this. This may have consequences for anyone
relying on these variables in configuration.

As per [1] mandatory configuration option is either baseurl, mirrorlist
or metalink.

EPEL repos use metalink and it's impossible to configure them via DNF
custom repos functionality right now.

Configuring veth pair MTU in the systemd-networkd .netdev files
does not set the correct MTU for the peer and there isn't
configuration option in the [Peer] section to do so [1].
This results in an MTU mismatch with peer having the default
(1500) value.

This change moves the MTU configuration from the .netdev file
to the [Link] section of the corresponding veth pair .network files.
Same approach is already recommended in [1] for the tun and
tap devices.

Because regexes defined by Kayobe are not strict enough, Kolla can build
container images unrelated to the deployment. For example, the default
service configuration will build:

- centos-binary-barbican-keystone-listener (matches keystone)
- centos-binary-prometheus-memcached-exporter (matches memcached)

This commit makes regexes stricter to avoid unecessary builds. Note that
some images are still built unecessarily, such as nova-compute-ironic
when ironic is disabled or neutron-metadata-agent-ovn when ovn is
disabled.

This allows us to include the correct branch when cloning repositories
in documentation.

Method adapted from OpenStack Ansible documentation. A backslash is
added on purpose before repository URLs to bypass highlighting which
makes them less readable (dark text on dark background).
