laravel5日志设置篇(1) - 记录开始和结束日志

想要实现的功能

[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]"}
