However, for some unknown errors like 301 and 305, we may not need to retry for it in some case.

And previously we use the max retry count which is always 10(hard code) to control the retry limit but for user, a changable max retry time duration may be more friendly.

And we want both the above two new added confiugration can be hot loaded.
