解决requests的logging日志打印大量INFO，DEBUG日志

在项目中使用logging记录日志文件，当此类使用了requests，查看log大量request请求存在在日志中。

Thu, 27 May 2021 17:36:11 connectionpool.py[line:203] INFO Starting new HTTP connection (1): xxx.xxx.xxxx.cn
Thu, 27 May 2021 17:36:11 connectionpool.py[line:383] DEBUG "POST //xxxx/auth/identity/connect/token HTTP/1.1" 200 None
Thu, 27 May 2021 17:36:11 connectionpool.py[line:203] INFO Starting new HTTP connection (1): xx.xxx.xxxx.cn
Thu, 27 May 2021 17:36:11 connectionpool.py[line:383] DEBUG "GET //xxxx/xx/scans/1000033 HTTP/1.1" 200 1315

导致大量无用写入。

requests官方文档中说明的各种阶段的日志等级.

INFO: New connections (HTTP or HTTPS)
INFO: Dropped connections
INFO: Redirects
WARN: Connection pool full (if this happens often increase the connection pool size)
WARN: Retrying the connection
DEBUG: Connection details: method, path, HTTP version, status code and response length

可以使用 logger = logging.getLogger(__name__) ,对于调用方可以使用getLogger获取和配置对象的日志.  比如, logging.getLogger("requests").setLevel(logging.INFO)
