Summary
Multi-thread uploads of multiple files from dataset to cloud storage.

When uploading 100 files, the time taken was:
- 15.5s with the new approach
- 50.9s with the old approach

This is a 3.3x speed up that is likely to increase with the number of files in the dataset and the number of threads available.

- Lift 10-worker limit for dataset file downloads

Fixes
