Support KMS-Encrypted Buckets

Description - Currently, Adobe can't support sending data to KMS-encrypted buckets. This is actually a requirement from our governance team and we needed to receive an exception just to proceed in the manner we do.

Why is this feature important to you - KMS is useful for all S3 buckets, and Adobe's SDK should be able to support sending data in that matter.

How would you like the feature to work - Support KMS encryption, assuming the role Adobe uses has that access.

Current Behaviour - Feeds will fail
