One server and one client example in FedCV object detection

Hi,

I build FedML platform using docker container provided by the authors.
To see the performance of simple one server and one client example, I run `run_server.sh` and `run_client.sh` scripts inside the object_detection/ directory. Then, I started receiving following state in server and client terminal

#Server side:

```
mqtt_s3.send_message: msg topic = fedml_yolov5_0_2
mqtt_s3.send_message: msg topic = fedml_yolov5_0_2

```

I suspect that there is some problem in the connection between client and server.
I am using the same PC for client and for server
Any hint and suggestion is highly appreciated !!!
