Add docker volume command

[jaudiger]

Reference: https://docs.docker.com/engine/reference/commandline/volume/

Proposed initial syntax (more can be added in future):

• Command: docker volume create volumeName

docker:
  description: "Create a volume"
  volume:
    name: volumeName

• Command: docker volume rm volumeName

docker:
  description: "Delete a volume"
  volume:
    name: volumeName
    absent: false

• Command: docker volume rm -f volumeName

docker:
  description: "Force deletion of a volume"
  volume:
    name: volumeName
    absent: false
    force: true

The volume command can be useful to create/delete a volume to share data between containers.
