Fixing shared volume permission

Fix shared-volume permission issue(s) (#13)

* No "data-paths" will be created in the image, in order to stop docker from mucking up permissions
* gpg-s3sync will now check all paths that it works with to make sure it can proceed effectively; if not it bails with descriptive error
* data-generateor split out into a seperate docker file and as a new service in `docker-compose.test.yml`, in order to emulate a real data generation service
* various improvements to the test script
* Added extra docker-ignores

Fixes previous release
