Multi-match query do not support match query options

According to [elasticsearch documentation](http://www.elasticsearch.org/guide/reference/query-dsl/multi-match-query/), the multi-match query support all other options in match query. However, the `Elastica\Query\MultiMatch` class do not support setting options of match query.

I have also directly make a multi-match query request to my local copy of elasticsearch server with match parameters and it seems working

```json
{
  "query": {
    "multi_match": {
      "query": "red shirt",
      "fields": [
        "post_content^1",
        "post_title^10"
      ],
      "operator": "and"
    }
  }
}
```

While at the moment we could use `setParam` to directly set the data, it would be nice to have the Multi-match Query class support this, I think.
