Fix host directory mounts on Windows

[maass-tv]

On Windows, it is not possible to mount host directories to a subfolder of a non-C: drive. Due to this restriction, having a workspace on another drive will make the docker run execution fail since the plugin tries to map the workspace into the container.

This fixes that by collecting all the non-C: drive volume mappings and handling those explicitly by mapping the entire drive into the container.
