想要实现的功能
记录Application的开始和结束日志
– 开始日志： URL请求或命令行记录
– 结束日志： 处理时间和内存使用峰值记录
例如：
[2017-10-19 23:06:00] local.INFO: -- Startup {"command":"php artisan list"}
[2017-10-19 23:06:00] local.INFO: -- Shutdown {"time":"36.955[ms]","memory":"10[mb]"}
[2017-10-19 23:11:37] local.INFO: -- Startup {"method":"GET","uri":"/v1/stocks"}
[2017-10-19 23:11:37] local.INFO: -- Shutdown {"time":"21.765[ms]","memory":"4096[kb]"}
