si Non-blocking HTTP client with no external dependencies.
This class implements an HTTP 1.1 client on top of Tornado's IOStreams.
Some features found in the curl-based AsyncHTTPClient are not yet
supported. In particular, proxies are not supported, connections
are not reused, and callers cannot select the network interface to be
used.

Only a single AsyncHTTPClient instance exists per IOLoop
in order to provide limitations on the number of pending connections.
``force_instance=True`` may be used to suppress this behavior.
Note that because of this implicit reuse, unless ``force_instance``
is used, only the first call to the constructor actually uses
its arguments. It is recommended to use the ``configure`` method
instead of the constructor to ensure that arguments take effect.
``max_clients`` is the number of concurrent requests that can be
in progress; when this limit is reached additional requests will be
queued. Note that time spent waiting in this queue still counts
against the ``request_timeout``.
``hostname_mapping`` is a dictionary mapping hostnames to IP addresses.
It can be used to make local DNS changes when modifying system-wide
settings like ``/etc/hosts`` is not possible or desirable (e.g. in
unittests).
``max_buffer_size`` (default 100MB) is the number of bytes
that can be read into memory at once. ``max_body_size``
(defaults to ``max_buffer_size``) is the largest response body
that the client will accept. Without a
``streaming_callback``, the smaller of these two limits
applies; with a ``streaming_callback`` only ``max_body_size``
does.
.. versionchanged:: 4.2
Added the ``max_body_size`` argument.
