<id>urn:sha1:1eeb3a5395529b40994d7e25f89a0a7cf9799132</id>
<content type='text'>
This reverts commit f8d4db54db8f2ab2c7f99f0fcbc456177d33ddad.

Reason for revert: Zun was deprecated due to the hard dependency on old version of docker and etcd. Right now, the problem was fixed.

This reverts commit 94a74f58c7891e41ca637c4e2a6450ca88cbfb56.

Reason for revert: Zun/Kuryr-libnetwork has switched to "local" scope which doesn't require docker 20 anymore. It should work for latest docker version. Related patches:

<content type='text'>
* Zun currently has a dependency on a combination of Docker and
  etcd that is no longer installable (or supported) in newer
  distros.
* These components are core dependencies of other systems and
  vendoring them will be very painful.
* Work to update Zun past this is scheduled for the 'C' cycle.
* If Zun regains compatibility, backports to this series will be
  considered.

* When the Debian job got upgraded from Bullseye
  to Bookworm, the non-voting Zun job started failing.
* This is because Debian Bookworm doesn't support the
  required Docker 20 pinning.
* Until Zun gains support for newer dependencies this
  job will keep failing.

<title>Zun: Add zun-cni-daemon to compute node</title>

Zun has a new component "zun-cni-daemon" which should be
deployed in every compute nodes. It is basically an implementation
of CNI (Container Network Interface) that performs the neutron
port binding.

If users is using the capsule (pod) API, the recommended deployment
option is using "cri" as capsule driver. This is basically to use
a CRI runtime (i.e. CRI plugin for containerd) for supporting
capsules (pods). A CRI runtime needs a CNI plugin which is what
the "zun-cni-daemon" provides.

The configuration is based on the Zun installation guide [1].
It consits of the following steps:
* Configure the containerd daemon in the host. The "zun-compute"
  container will use grpc to communicate with this service.
* Install the "zun-cni" binary at host. The containerd process
  will invoke this binary to call the CNI plugin.
* Run a "zun-cni-daemon" container. The "zun-cni" binary will
  communicate with this container via HTTP.

This also enables Placement when Zun is enabled like Kolla Ansible
already does with Nova.
