Add file to the reno documentation build to show release notes for
stable/wallaby.

Use pbr instruction to increment the minor version number
automatically so that master versions are higher than the versions on
stable/wallaby.

Adds a new 'os_distribution' variable which can be used to select the OS
distribution, with sensible defaults for other variables. The default
value is 'centos'.

This patch changes the default value for the '*_bootstrap_user'
variables from using the $USER environment variable to using fixed
defaults equal to the os_distribution variable. This aligns with the
standard user configured in most cloud images, and images created via
DIB.

Note that we are continuing to use a CentOS based IPA image, since we
have been unable to get IPA to build for Ubuntu.

On CentOS, when using the MichaelRigart.interfaces role, defining a VLAN
interface implies the existence of its parent interface. This is handled
via the CentOS network interface scripts. With systemd-networkd, the
parent interface is not implicit, and must be configured. The parent
interface network configuration file needs to contain this:

    [Network]
    VLAN = eth0.42

This change adds support for these implied parent interfaces. It also
removes the Broadcast = true option, which was added in an attempt to
fix an issue but is not supported in the [Network] section, and
generates a warning:

    Unknown key name 'Broadcast' in section 'Network', ignoring.

Cleaning was disabled by default in Bifrost
(Ie1198768889bd468176cd68c8ccb48791c724262) until the Victoria release,
when the default was changed. The 'kayobe overcloud provision' command
does not handle cleaning states when moving nodes from manageable to
available. This can lead to provisioning failures.

This change disables cleaning to maintain backwards
compatibility with earlier versions of Kayobe.

Based on the discussions from recent Kolla meetings [1][2][3],
we established that, to avoid the DockerHub pull limit issues
in our CI, we will try using quay.io.

The images have already been published via Kolla CI
for master/Wallaby [4] and Victoria [5].

This change applies only to CI.
The user-facing move is yet to be discussed.

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

All instances of 'kayobe control host bootstrap' in the development
scripts use a helper function, except for during seed_hypervisor_deploy.
The helper adds a retry mechanism to combat flakiness often seen during
Ansible Galaxy installs.

This change fixes the issue.
