This is only supported on CentOS for now due to limitations of the
Ansible role used to configure tuned.

CentOS repositories were renamed following the separation of CentOS
Linux and Stream. This change updates their names when using a local
mirror. It also removes the old files.

Some hosts in the kayobe inventory might not be in the kolla-ansible
inventory so it makes sense for kayobe to manage NTP.

This change adds support for policy-based routing via systemd-networkd.
Due to differences in the configuration mechanism, routing policy
rules are configured via dicts for Ubuntu, while remaining as strings
on CentOS. Ideally we would support both formats.

This change adds support for network configuration via systemd-networkd
on Ubuntu systems.

This is implemented via an Ansible Galaxy role,
stackhpc.systemd_networkd which was forked from
aruhier.systemd_networkd. Several improvements were made in
https://github.com/stackhpc/ansible-role-systemd-networkd/pull/1,
including:

* Add support for removing unexpected config files
* Use become where necessary
* Refactor config generation into a single task to improve performance

The systemd_networkd role does not add much abstraction on top of the
systemd-networkd configuration file format, which provides a lot of
flexibility at the expense of additional code in Kayobe. This code is
implemented as filter plugins, similarly to the existing
MichaelRigart.interfaces role.

This patch includes support for:

* Ethernet interfaces
* bridges
* bonds
* VLANs
* virtual Ethernet pairs (to connect Linux bridges and OVS bridges)
* static IP addresses
* static routes
* MTU

Some network attributes are currently not supported for
systemd-networkd:

* rules
* route options
* ethtool_opts
* zone
* allowed addresses

This can be advantageous in deployments with a data security
requirement.

Tests various non-default configuration:

* Custom users
* Network interfaces, VLANs, bridges, bonds
* Software RAID
* LVM & docker devicemapper
* timezone
* Package mirrors
* yum-cron / DNF automatic

This improved test coverage allows us to be more confident about these
features working on CentOS 8.
