Limit req: "delay=" parameter.
This parameter specifies an additional "soft" burst limit at which requests
become delayed (but not yet rejected as it happens if "burst=" limit is
exceeded). Defaults to 0, i.e., all excess requests are delayed.
Originally inspired by Vladislav Shabanov
(http://mailman.nginx.org/pipermail/nginx-devel/2016-April/008126.html).
Further improved based on a patch by Peter Shchuchkin
(http://mailman.nginx.org/pipermail/nginx-devel/2018-October/011522.html).
