Connection to influx still active even after calling influxdb.close();

Connection to influx still active even after calling `influxdb.close();`

Here is my **Test Code**

```
public static void main (String[]args){
InfluxDB influxDBConnection;

for (int i = 0; i < 10; i++) {
try {
QueryResult queryResult;
influxDBConnection = InfluxDBFactory.connect("url", "username", "password");
queryResult = influxDBConnection.query(new Query("select value1 from test_measurement1", "test_db"));
System.out.println(queryResult.getResults().get(0).getSeries().get(0).getValues().get(0).get(1).toString());
influxDBConnection.close();
Thread.sleep(10000);
} catch (Exception e) {
e.printStackTrace();
}
}
}
```

After execution of following code 10 connections are made even after calling the close method.
I checked the number of connection made to influxdb through `netstat`.

Is there any way to close the existing influx connection?

Inizia riproducendo il loop fornito e verificando il comportamento della connessione con netstat. Leggi il ciclo di vita di InfluxDBFactory.connect e InfluxDB.close documentato o esposto dal client; il lavoro è completato quando chiamate ripetute a connect/close non lasciano attive le connessioni osservate.
