    Shortcuts for generating request headers.

    :param keep_alive:
        If ``True``, adds 'connection: keep-alive' header.

    :param accept_encoding:
        Can be a boolean, list, or string.
        ``True`` translates to 'gzip,deflate'.  If the dependencies for
        Brotli (either the ``brotli`` or ``brotlicffi`` package) and/or Zstandard
        (the ``zstandard`` package) algorithms are installed, then their encodings are
        included in the string ('br' and 'zstd', respectively).
        List will get joined by comma.
        String will be used as provided.

    :param user_agent:
        String representing the user-agent you want, such as
        "python-urllib3/0.6"

    :param basic_auth:
        Colon-separated username:password string for 'authorization: basic ...'
        auth header.

    :param proxy_basic_auth:
        Colon-separated username:password string for 'proxy-authorization: basic ...'
        auth header.

    :param disable_cache:
        If ``True``, adds 'cache-control: no-cache' header.

    Example:

    .. code-block:: python

        import urllib3

        print(urllib3.util.make_headers(keep_alive=True, user_agent="Batman/1.0"))
        # {'connection': 'keep-alive', 'user-agent': 'Batman/1.0'}
        print(urllib3.util.make_headers(accept_encoding=True))
        # {'accept-encoding': 'gzip,deflate'}

    transforms them into an iterable of chunks to pass to
    socket.sendall() and an optional 'Content-Length' header.

    A 'Content-Length' of 'None' indicates the length of the body
    can't be determined so should use 'Transfer-Encoding: chunked'
    for framing instead.
