Query string time zone not working

[dadoonet]

If you define exactly the same date range query using either DATE+0200 notation or DATE and set timezone: +0200, elasticsearch gives back different results:

DELETE foo
PUT /foo
{
  "mapping": {
    "tweets": {
      "properties": {
        "tweet_date": {
          "type": "date"
        }
      }
    }
  }
}

POST /foo/tweets/1/
{
  "tweet_date": "2015-04-05T23:00:00+0000"
}
POST /foo/tweets/2/
{
  "tweet_date": "2015-04-06T00:00:00+0000"
}

GET /foo/tweets/_search?pretty
{
    "query": {
        "query_string": {
            "query": "tweet_date:[2015-04-06T00:00:00+0200 TO 2015-04-06T23:00:00+0200]"
        }
    }
}
GET /foo/tweets/_search?pretty
{
    "query": {
        "query_string": {
            "query": "tweet_date:[2015-04-06T00:00:00 TO 2015-04-06T23:00:00]",
            "time_zone": "+0200"
        }
    }
}

This PR fixes it and will also allow us to add the same feature to simple_query_string as well in another PR.

Closes #10477.

@jpountz actually simple_query_string still not supports ranges in Lucene so we can't have that. :(
