Support the quantile for response time

It should be important for the module users to fetch the response time quantile for various use cases.
I consider that it is suitable for using libgkc which is the library within the high performance http server h2o

According this code, it follows the algorithm which is written in this paper. Thus it is efficiency spatial complexity for that calculate.
