This PR adds a "transfer_manager" module which enables concurrent downloads and uploads of multiple files via the use of a thread pool. Transfer Manager is a preview feature and the API and behavior are subject to change before a GA launch of the feature in the future. A warning is emitted on import to this effect. Please do not hesitate to submit bugs and general feedback, positive or negative, by opening a github issue.
The performance of this feature is sensitive to the value of the "threads" parameter and the specifics of the environment and workload. Read the docstrings on "threads" and experiment to find what works best for each use case.
