Yusuke Kuoka 4b557dc54c Add logging transport to log HTTP requests in log level -3 ... The log level -3 is the minimum log level that is supported today, smaller than debug(-1) and -2(used to log some HRA related logs). This commit adds a logging HTTP transport to log HTTP requests and responses to that log level. It implements http.RoundTripper so that it can log each HTTP request with useful metadata like `from_cache` and `ratelimit_remaining`. The former is set to `true` only when the logged request's response was served from ARC's in-memory cache. The latter is set to X-RateLimit-Remaining response header value if and only if the response was served by GitHub, not by ARC's cache.		2022-02-19 12:22:53 +00:00
