    This wrapper keeps track of our underlying CRT client, the lock used to
    acquire it and the region we've used to instantiate the client.

    Due to limitations in the existing CRT interfaces, we can only make calls
    in a single region and does not support redirects. We track the region to
    ensure we don't use the CRT client when a successful request cannot be made.

    Boto3 client must use same signing region and credentials
    as the CRT_S3_CLIENT singleton. Otherwise fallback to classic.
