Azure service bus send heartbeat to keep connection alive

[ShirishGajera]

Is your feature request related to a problem? Please describe.
If I understand correctly if there are no activity for 4 minutes on Azure service bus connection client, connection will die and that what I am hitting. I am trying to complete the message and seeing this exception.

Unexpected error occurred (ValueError('Link already closed.')). Handler shutting down.
Traceback (most recent call last):
  File "/usr/local/lib/python3.10/dist-packages/azure/servicebus/aio/_base_handler_async.py", line 260, in _do_retryable_operation
    return await operation(**kwargs)

    raise ValueError("Link already closed.")
ValueError: Link already closed.

Describe the solution you'd like
I want to set heartbeat to keep the connection live when creating client using from_connection_string()

Describe alternatives you've considered
I am currently recreating client every 3 minutes as work around

If there is already existing solution please let me know

Even I am facing the same challenge. The python sdk doesn't have proper connection management / pooling feature for service bus. So I built my own asyncio based connection pooling based of a FIFO asyncio.Queue. However, the connection drops due to inactivity for some time, and for n requests, it takes 10 seconds each to refresh the connections, where n is the pool size.
