Provides translucent api for moving large tasks out of request response

Install: `php composer.phar require bazilio/yii2-async:dev-master`

##### Requirments:
- php >=5.4
- Transports:
- `yii\db\Connection`
- [php-amqp](https://github.com/pdezwart/php-amqp)
- [yii2-redis](https://github.com/yiisoft/yii2-redis)

##### Using with AMQP:
`php composer.phar require pdezwart/php-amqp:dev-master`

main.php:
```php
'components' => [
'async' => [
'class' => 'bazilio\async\AsyncComponent',
'transportClass' => 'bazilio\async\transports\AsyncAmqpTransport',
'transportConfig' => [
'host' => 'localhost',
'login' => 'guest',
'password' => 'guest',
'vhost' => 'yii',
'exchangeName' => 'yii'
]
]
]
```

##### Using with Redis:
`php composer.phar require yiisoft/yii2-redis:*`

main.php:
```php
'components' => [
'redis' => [
'class' => 'yii\redis\Connection',
'hostname' => 'localhost',
'port' => 6379,
'database' => 0,
'dataTimeout' => -1, // important for daemon and blocking queries
],
'async' => [
'class' => 'bazilio\async\AsyncComponent',
'transportClass' => 'bazilio\async\transports\AsyncRedisTransport',
'transportConfig' => [
'connection' => 'redis',
]
]
]
```

##### Using with MySQL (probably any sql, but tested only with mysql)

main.php:
```php
'components' => [
'db' => [
'class' => 'yii\db\Connection',
'dsn' => 'mysql:host=localhost;dbname=yii2advenced',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
],
'async' => [
'class' => 'bazilio\async\AsyncComponent',
'transportClass' => 'bazilio\async\transports\AsyncMysqlTransport',
'transportConfig' => [
'connection' => 'db',
]
]
]
```

Apply migrations:
```php
./yii migrate/up --migrationPath=@vendor/bazilio/yii2-async/migrations
```

##### Usage:

#### Create and send:
Test class example:
```php
class DownloadTask extends AsyncTask
{
public $url;
public $file;
public static $queueName = 'downloads';

public function execute()
{
return file_put_contents($this->file, file_get_contents($this->url));
}
}

// create task
$task = new DownloadTask(['url' => 'http://localhost/', 'file' => '/tmp/localhost.html']);
\Yii::$app->async->sendTask($task);
```

Or call external method:
```php
$task = new AsyncExecuteTask([
'class' => 'common\components\MyDownloaderComponent',
'method' => 'download',
'arguments' => ['url' => 'http://localhost/', 'file' => '/tmp/localhost.html']
]);

$task::$queueName = 'downloads';

if (YII_ENV !== 'prod') {
$task->execute();
} else {
Yii::$app->async->sendTask($task);
}
```

#### Execute:

Bash way:

Fill console config:
```php
'controllerMap' => [
'async-worker' => [
'class' => 'bazilio\async\commands\AsyncWorkerCommand',
],
],
```

Run:
```bash
# Process and exit on finish
./yii async-worker/execute downloads
# Process and wait for new tasks (only redis)
./yii async-worker/daemon downloads
```

Code way:

```php
while ($task = \Yii::$app->async->receiveTask('downloads')) {
if ($task->execute()) {
\Yii::$app->async->acknowledgeTask($task);
}
}
```
