Print a message if requested ports are in use

[varunsh-xilinx]

Describe the bug
If the server ports are already in use, the server executable ends with no error message and no logs, making it hard to identify what went wrong.

To Reproduce
Steps to reproduce the behavior:

1. Start the deployment container with --net=host
2. Start a second deployment container with --net=host. It ends immediately with no error.

Expected behavior
There should be an error message if the requested port is in use.

The error is coming from Trantor, which just exits if it can't bind to the requested port. I've raised 261 for it
