URL: https://github.com/apache/inlong/issues/11175
### What happened
The current MqttSource solution may cause message loss
### What you expected to happen
```java
@Override
public void messageArrived(String topic, MqttMessage message) throws
Exception {
Map<String, String> headerMap = new HashMap<>();
headerMap.put("record.topic", topic);
headerMap.put("record.messageId", String.valueOf(message.getId()));
headerMap.put("record.qos", String.valueOf(message.getQos()));
byte[] recordValue = message.getPayload();
mqttMessagesQueue.offer(new DefaultMessage(recordValue, headerMap), 1,
TimeUnit.SECONDS);
}
```
Due to the timeout mechanism of blocking queue
offers（`mqttMessagesQueue.offer(new DefaultMessage(recordValue, headerMap), 1,
TimeUnit.SECONDS);`）, messages may be lost when the queue is full
### How to reproduce
The mqtt production speed is higher than the consumption speed. When the
blocking queue is filled, messages will be lost.
