Description

In order to access S3 using temporary credentials (from STS), users must supply a session token in addition to the usual access key and secret key.

However, currently, the S3FileSystem class only accepts access_key and secret_key arguments. The only workaround is to provide the session token as an environment variable, but this not ideal for a variety of reasons.

This is a request to allow an optional session_token argument when initializing the S3FileSystem.
