Tomas Hozza 080b64c12c cloudapi: Don't return upload type in UploadStatus for now
Upload target type is currently not returned form the worker, but
hardcoded in the cloudapi code to always return "aws". This make testing
of the cloudapi for other cloud providers quite complicated.

Since extending the target status information returned from the
worker is currently in progress, work around the situation for now
by returning an empty string as the upload type.

This will allows other types of upload targets to be tested as part of
cloudapi test case.
