MQTT Publisher & Subscriber - "Random Suffix" check box is checked about mqttjmeter HOT 1 OPEN

Hi Swapnil,

I believe this is a bug in the code. Here is how I was able to fix it.

1. Modify the MQTTPublisherGui.java file as below.
2. Build and generate a new mqtt-jmeter.jar and place them in your JMETER/lib/ext folder.
3. Reopen JMeter tool.

`public void configure(TestElement el) {
....
mqttUser.setEnabled(useAuth.isSelected());
mqttPwd.setEnabled(useAuth.isSelected());

            //Adding the missing "Set" for the following UI elements.
    clientId.setText(sampler.getCLIENT_ID());
    suffixClientId.setSelected(sampler.useRandomSuffix());
    this.connectionPerTopic.setSelected(sampler.isOneConnectionPerTopic());

            ......

}`
