    This class is inspired by requests.adapters.HTTPAdapter, but has been
    boiled down to meet the use cases needed by botocore. For the most part
    this classes matches the functionality of HTTPAdapter in requests v2.7.0
    (the same as our vendored version). The only major difference of note is
    that we currently do not support sending chunked requests. While requests
    v2.7.0 implemented this themselves, later version urllib3 support this
    directly via a flag to urlopen so enabling it if needed should be trivial.
