Using the elasticsearch DebugPanel
----------------------------------
The yii2 elasticsearch extensions provides a `DebugPanel` that can be integrated with the yii debug module
an shows the executed elasticsearch queries. It also allows to run these queries on different cluster nodes
an view the results.
Add the following to you application config to enable it:
```php
// ...
'preload' => 'debug',
'modules' => [
'debug' => [
'class' => 'yii\\debug\\Module',
'panels' => [
'elasticsearch' => [
'class' => 'yii\\elasticsearch\\DebugPanel',
],
],
],
],
// ...
```
