title: How to create multiple connections in angular 6 using ngx-mqtt library?
body: <p>I need to connect to multiple brokers from the same angular 6 app.</p>
  
  <p>When importing MqttModule, we pass the config to it as:</p>
  
  <pre><code>imports: [...
  MqttModule.forRoot(MQTT_SERVICE_OPTIONS),
  ...]
  </code></pre>
  
  <p>I tried creating 2 separate modules on same hierarchical level and passing different config and setting up the connections, but it is not working.</p>
  
  <p>I think it creates services at the root level and we cannot create a separate connection in different modules.</p>
  
  <p>Can we even create multiple connections? If so, how?</p>
