* Split TransformStream and TransformProcess out of TransformHandler
* TestFileInfo to FileInfo
* Removed HttpRequestTests as it adds nothing now the controller is in the base
* Initialised the internal context to TranformRequest tests
* Rename AbstractQueueTransformServiceIT to AbstractQueueTest and change names of subclasses
Cleaned up the logic and added a comment to say what it was doing (sends messages ok, but fails the transform)
* Clean up application-default.yaml values (duplicate values)
* Renamed probe test files to be probe.???
* Moved iptc reference info to model rather than having a separate models directory
* Use InputStream and OutputStream in metadata extractors rather than Files.
