Describe the problem

upload_data() under sessions.py can not upload to encrypted s3 buckets right now. Fortunately, The boto3 function that upload_data() is based on, upload_file(), can accept 'ExtraArgs' as a parameter, in which the encryption key and such can be defined.

For example, upload_data may look like the following, with ExtraArgs being passed to upload_file
upload_data(....,ExtraArgs = {'ServerSideEncryption':'aws:kms', 'SSEKMSKeyId':'alias/aws/s3'})

note that estimator uses a different format to pass in the KMSKEY info. Perhaps there is a standard way of passing this info.
