Configuration for default logging | 日志管理

sentinel默认日志打印对资源有损耗，而且sentinle-record.log等日志未开放配置开关，建议开放配置，提供关闭日志打印、配置日志文件自动清理等功能，目前的模式用在生产环境真的很麻烦。

The issue specifically mentions Sentinel's default logging and sentinel-record.log; start by locating the logging configuration entry points and how that file is created. Done means production users can disable log output and configure automatic log-file cleanup, with the relevant behavior covered by tests.
