Creates an INSERT command.

For example,

```php
$connection->createCommand()->insert('user', [
'name' => 'Sam',
'age' => 30,
])->execute();
```

The method will properly escape the column names, and bind the values to be inserted.

Note that the created command is not executed until [[execute()]] is called.

Passing of [[yii\db\Query|Query]] is available since version 2.0.11.
@return $this the command object itself
