Add support to use mountpoint-s3 as a docker volume driver using a plugin

[aek]

Tell us more about this new feature.

For those who are interested in using this project in docker projects I have created a Docker Volume Plugin in order facilitate the usage of mountpoint-s3 in Docker Compose via a driver and driver_opts.

You could find the plugin public and ready to be installed from DockerHub
https://hub.docker.com/r/aekis/docker-mount-s3

The project is also hosted on Github
https://github.com/aekis-dev/docker-mount-s3

Example usage:

name: fe4d6eca
services:
  service_name:
    image: image_name
    volumes:
    - type: volume
      source: volume_name
      target: /s3/bucket/data
  volumes:
    volume_name:
      driver: aekis/docker-mount-s3
      driver_opts:
        bucket: bucket_name
        AWS_ACCESS_KEY_ID: XXXXXXAWS_ACCESS_KEY_IDXXXXXXX
        AWS_SECRET_ACCESS_KEY: XXXXXXXXXXXXAWS_SECRET_ACCESS_KEYXXXXXXXXXXXX
        o: --allow-delete --allow-overwrite --allow-other --region=us-east-1

Hi, thank you for the feature request - that project you've written looks interesting!

It's unlikely that we will be wanting to include this in our repositories, but if there are any small features we could add to unblock your usecase, feel free to open another feature request for them.

Hi @muddyfish
Thanks for your comments, it's ok, I only wanted to showcase another usage of this project mountpoint-s3 to directly mount docker volumes using the driver I have suggested
