Title: Fix server cluster configuration

This fixes the `Elastica\Client::_initConnections` method so that the following code in the documentation works:

```php
$elasticaClient = new \Elastica\Client(array(
'servers' => array(
array('host' => 'localhost', 'port' => 9200)
array('host' => 'localhost', 'port' => 9201)
)
));
```

Before, the code was referencing an uninitialized variable (`$_config`), and it only assumed a single connection.
