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.

CentOS 8 removes interfaces from their bridge during ifdown, and removes
the bridge if there are no interfaces left. When Kayobe bounces veth
links plugged into the bridge, it causes the bridge which has the IP we
are using for SSH to be removed. Use a dummy interface in CI to avoid
this problem.

Kolla-ansible has dropped all CentOS 7 jobs on master now, and prechecks
only allow CentOS 7 hosts. Drop all CentOS 7 jobs. We will have to run
without upgrade jobs in place until Train supports CentOS 8.

Attempts affect pre failures.  This means we can increase stability of
jobs by rejecting nodes that fail pre without failing runs at the same
time (unless we are really unlucky and hit b0rken nodes 5 times in a
row).

Both docs-on-readthedocs and build-openstack-sphinx-docs contain a build
job - a different one: the current openstack-tox-docs and the obsolete
build-openstack-sphinx-docs. Remove the obsolete template and thus
avoid building docs twice for each change.

Change-Id: I358641d29304815eec6c699ae7e20da1e069443d

This was found not to work, and prevents releases from being made.

The cause of the issue is that the trigger-readthedocs-webhook job (in
project-config) is marked as 'final', meaning that a non-trusted Zuul
config source can't override its variables. Instead, you're supposed to
use the trigger-readthedocs-webhook project template, but only one
instance of this can be instantiated by design.

Let's revert to manually updating the release notes for now.

playbooks for preparing and executing diagnostics, plus other

Attempts have been made to correct repository namespaces and

Use master branch of:

* Kolla

Also, use the infra docker registry mirror at port 8082 which does not
have any path component in its URL, and so works with Docker CE.

There is currently no coverage of upgrades in CI, which leaves us open
to regression in this infrequently tested but crucial area. This change
adds the required scripts and Zuul configuration.

A control plane is first deployed using the Kayobe stable/pike branch
and associated default configuration. The control plane is tested by
deploying then deleting a server instance. An upgrade to Queens is
performed, using the Kayobe master branch, or code in review if
applicable. The upgraded control plane is tested by deploying then
deleting a second server instance.

A workaround was required to restart the nova_compute service after the
upgrade, since the SIGHUP sent to it by Kolla Ansible during upgrade
appeared to be putting it into a degraded state.

A future improvement to this test could be to leave a server instance
running during the upgrade.

The Kayobe development configuration has moved to
openstack/kayobe-config-dev. It was previously hosted at
stackhpc/dev-kayobe-config on Github.

This change updates the Zuul configuration and development documentation
to use the new location. It also uses a location for the kayobe source
code that works when kayobe is not the repository against which the code
review is targetted. This allows us to run kayobe jobs for
kayobe-config-dev changes.

Configuration for the seed VM and seed hypervisor development
environments is not yet supported by kayobe-config-dev, so the
documentation references a branch in my personal fork on Github.

Changes to kolla inventory files were made by comparing the multinode

Kolla ansible added the concept of inner-compute and external-compute,

Adds a new CI job, kayobe-seed-centos, that deploys a single VM as a
seed host. The VM provided by Zuul is configured as the seed, rather
than a seed hypervisor that provisions a seed VM using nested virt.

This approach should be more reliable, faster, and easier to get
working, at the expense of not testing the seed hypervisor code paths.

Currently the seed services are deployed, but not tested. A future
change could test discovery and provisioning of an overcloud host using
the seed.
