docs: improve automated seed development info

* add 'bridge_type: linuxbridge' to tenks configuration to avoid
  dependency on OVS
* extend seed development environment testing to include overcloud
  provisioning and deployment
* remove seed hypervisor and seed VM environments. These are very
  stale, and largely replaced by a-universe-from-nothing. Add a link to
  that workshop on the same page

The `Universe from Nothing

for more advanced testing scenarios involving a seed hypervisor, seed VM, and

Seed Hypervisor
===============
The seed hypervisor development environment is supported for CentOS 8. The
system must be either bare metal, or a VM on a system with nested
virtualisation enabled.
Preparation
-----------
The following commands should be executed on the seed hypervisor.
Clone the Kayobe repository::
git clone https://opendev.org/openstack/kayobe.git
Change the current directory to the Kayobe repository::
cd kayobe
Clone the ``add-seed-and-hv`` branch of the ``kayobe-config-dev`` repository to
``config/src/kayobe-config``::
mkdir -p config/src
git clone https://github.com/markgoddard/dev-kayobe-config -b add-seed-and-hv config/src/kayobe-config
Inspect the Kayobe configuration and make any changes necessary for your
environment.
Usage
-----
Run the ``dev/install-dev.sh`` script to install Kayobe and its dependencies in a
Python virtual environment::
./dev/install-dev.sh
.. note::
This will create an :ref:`editable install <installation-editable>`.
It is also possible to install Kayobe in a non-editable way, such that
changes will not been seen until you reinstall the package. To do this you
can run ``./dev/install.sh``.
Run the ``dev/seed-hypervisor-deploy.sh`` script to deploy the seed
hypervisor::
./dev/seed-hypervisor-deploy.sh
Upon successful completion of this script, the seed hypervisor will be active.
.. _contributor-automated-seed-vm:
Seed VM
=======
The seed VM should be deployed on a system configured as a libvirt/KVM
hypervisor, using :ref:`contributor-automated-seed-hypervisor` or otherwise.
Preparation
-----------
The following commands should be executed on the seed hypervisor.
Clone the Kayobe repository::
git clone https://opendev.org/openstack/kayobe.git
Change to the ``kayobe`` directory::
cd kayobe
Clone the ``add-seed-and-hv`` branch of the ``kayobe-config-dev`` repository to
``config/src/kayobe-config``::
mkdir -p config/src
git clone https://github.com/markgoddard/dev-kayobe-config -b add-seed-and-hv config/src/kayobe-config
Inspect the Kayobe configuration and make any changes necessary for your
environment.
If using Ubuntu, configure the OS distribution::
sed -i -e 's/#os_distribution:/os_distribution: ubuntu/' config/src/kayobe-config/etc/kayobe/globals.yml
Usage
-----
Run the ``dev/install-dev.sh`` script to install Kayobe and its dependencies in a
Python virtual environment::
./dev/install-dev.sh
.. note::
This will create an :ref:`editable install <installation-editable>`.
It is also possible to install Kayobe in a non-editable way, such that
changes will not been seen until you reinstall the package. To do this you
can run ``./dev/install.sh``.
Run the ``dev/seed-deploy.sh`` script to deploy the seed VM::
./dev/seed-deploy.sh
Upon successful completion of this script, the seed VM will be active. The
seed VM may be accessed via SSH as the ``stack`` user::
ssh stack@192.168.33.5
Upgrading

It is possible to test an upgrade by running the ``dev/seed-upgrade.sh``
script::
