Method reset_stream

awscli/botocore/awsrequest.py:512–533

Resets the streaming body to it's initial position. If the request contains a streaming body (a streamable file-like object) seek to the object's initial position to ensure the entire contents of the object is sent. This is a no-op for static bytes-like body types.
