[SF] Symfony 在 console 中结合 Workerman

在web框架的console中，命令不再是直接指定入口文件，如以往 php test.php start，而是类似 php app/console do 的形式。

workerman 对命令的解析是 parseCommand 方法，里面主要是处理 $argv 全局变量。

那么我们只需要在自己的逻辑中对其重新赋值，满足 $argv[1] 是动作 start | stop | restart | ... 即可，那么剩余workerman参数就是 $argv[2]，依次类推。

Symfony2 command:

namespace AppBundle\Command;

use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

use Workerman\Connection\TcpConnection;
use Workerman\Worker;
