    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'.
        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.
