This change replaces Kind with a might lighter K8s variation K3D.
Many of our manifests have also been consolidated.
Other key changes have been highlighted below:
* Utilise K3D Traefik Ingress
* Automatically provision all manifests, removing the abundance of shell scripts
* Expose Traefik and K8s dashboards through the Ingress
The initial deps backlog has mostly been addressed now, this along with some reshuffling and changes to node jobs/priority means we should be able to turn auto rebase back on.
This change is to ensure that our CI workers are not flooded with jobs that fail.
This setting will be removed when the initial backlog has been merged.
