Add Support for Docker Swarm / Repackage as Docker Plugin

# Describe the feature you'd like to have #

Recently published Docker 23.0.0 added CSI support for Swarm mode so it is possible to use CSI drivers with it but they have to be packaged as Docker plugin.

# What is the value to the end user? (why is it a priority?) #

Docker Swarm users would gain the ability to use ceph in Docker Swarm via CSI instead of relying on bind mounting volumes.

# How will we know we have a good solution? (acceptance criteria) #

- Packaged the CSI driver for Docker.
- Able to create a cluster volume via the docker cli

# Additional context #

You can find more information [here]( https://github.com/olljanat/csi-plugins-for-docker-swarm). Hetzner CSI has already merged a [PR that adds support](https://github.com/hetznercloud/csi-driver/pull/376)

Start by reading the Docker Swarm CSI packaging context in this issue, the referenced csi-plugins-for-docker-swarm project, and Hetzner CSI PR #376. Identify the repository entry points and packaging configuration involved, then validate the result by creating a cluster volume through the Docker CLI. Done means the CSI driver is packaged as a Docker plugin and that volume creation works in a Swarm cluster.
