Recently we encountered a problem when using hyper.

After the client sent the request, it received response 431 Request Header Fields Too Large. After investigation, we found that hyper sets an upper limit on the number of headers, and this upper limit is a fixed and non-configurable value.

#3283 also encountered similar problems.

This PR sets max_headers to a configurable value. Its default value remains the same as the previous code, and we can set this value when needed.

Additionally, unit tests have been added and the current code passes.

Thanks for the thorough PR! I welcome adding the option, but I want to make sure we continue to stay as fast as possible.
