test number of headers fields and size.

Add --limit-request-fields (limit_request_fields) and
--limit-request-field-size (limit-request-field-size) options.

- limit_request_fields:

    Value is a number from 0 (unlimited) to 32768. This parameter is
    used to limit the number of headers in a request to prevent DDOS
    attack. Used with the `limit_request_field_size` it allows more
    safety.

- limit_request_field_size:

    Value is a number from 0 (unlimited) to 8190. to set the limit
    on the allowed size of an HTTP request header field.
