To reproduce:
1. Sync the IoT with a 17 database
2. Once it is set up, force shut down the server by Ctrl+C 2 times
3. Wait a few seconds:
=> crash of `WebsocketClient` thread with the following traceback:
```
Traceback (most recent call last):
File "/usr/lib/python3.11/threading.py", line 1038, in _bootstrap_i>
self.run()
File "/home/pi/odoo/addons/hw_drivers/websocket_client.py", line 83>
self.ws.run_forever()
File "/usr/local/lib/python3.11/dist-packages/websocket/_app.py", l>
raise WebSocketException("socket is already opened")
websocket._exceptions
WebSocketException
socket is already opened
```
The IoT synchronised servers can stop in 2 ways that we need to handle:
A. Gracefully (Ctrl+C):
In this case a disconnection signal is sent to the IoT-box
The websocket is properly closed, but it needs to be established a new connection when
the server will be back.
Solution: `while True` loop as `run_forever` will return on close.
`time.sleep` for the reconnection delay
B. Forced/killed (Ctrl+C 2 times):
In this case there is no disconnection signal received
Solution: use `reconnect` that will automatically take care re-attempting a connection
This will also happen with the graceful quit as `reconnect` will trigger if the server
is offline while attempting the new connection
In both case, we perform a reconnection attempt with a delay of 10 seconds to avoid
spamming the database
After this commit:
The websocket will reconnect itself automatically after 10 seconds
if the connection is disrupted
