feat: add hook action for http server

[kocoten1992]

Previously, there is no way (?) to hook up and run a script before http start.

This patch allowed user to extends our class with hookAction run custom script before starting server up.

Good! There is an example to show how i can implement this on a right way?

[kocoten1992]

@leocarmo you can extends it normally, it will overwrite the default command

<?php

namespace App\Console\Commands;

use SwooleTW\Http\Commands\HttpServerCommand;

class TestCommand extends HttpServerCommand
{
    protected $signature = 'swoole:http {action : start|stop|restart|reload|infos}';

    protected function hookAction()
    {
        echo 'hook between init and run';
    }
}
