Upload multiple files to S3.

path_to_key is a function that converts a file path to the key it should have in S3. The provided strip_prefix function should cover most use cases.

s3_upload_files provides counting of uploaded files and bytes through the progress closure:

For common use cases it is adviced to use files_recursive as files.

progress will be called after the upload of each file, with some data about that upload. The first usize parameter is the number of this file in the upload, while RequestReport holds more data such as size in bytes, and the duration of the upload. It is thus possible to report progress both in amount of files, or amount of bytes, depending on what granularity is desired. progress returns a generic F: Future to support async operations like, for example, logging the results to a file; this future will be run as part of the upload algorithm.

default_request constructs the default request struct - only the fields bucket, key, body and content_length are overwritten by the upload algorithm.
