add volume_driver Docker configuration file option

Jason Roehmrequested to merge
jasonroehm/gitlab-ci-multi-runner:docker-volume-driver into master

What does this MR do?

This adds support in config.toml for Docker's volume-driver option.

Why was this MR needed?

Along with the existing support for Docker options like volumes, devices, etc., some setups need to access the volume-driver option (e.g. containers that wish to use NVIDIA GPUs using the nvidia-dockerplugin.

Are there points in the code the reviewer needs to double check?

None that I know of; it is quite straightforward, as it involves just reading one more string option from the configuration file and passing it directly to the HostConfig section to go-dockerclient.

Does this MR meet the acceptance criteria?

  • Branch has no merge conflicts with master (if you do - rebase it please)
