kafka python driver creates warnings and errors in shotover

[rukai]

When python producer terminates it generates this log in shotover (for whichever node it was connected to at the time i think:

 17 03:51:10 i495b4929 shotover-proxy[147000]: 2024-04-17T03:51:10.530285Z ERROR shotover::server: connection was unexpectedly terminated
Apr 17 03:51:10 i495b4929 shotover-proxy[147000]: Caused by:
Apr 17 03:51:10 i495b4929 shotover-proxy[147000]:     0: Chain failed to send and/or receive messages, the connection will now be closed.
Apr 17 03:51:10 i495b4929 shotover-proxy[147000]:     1: KafkaSinkCluster transform failed
Apr 17 03:51:10 i495b4929 shotover-proxy[147000]:     2: Invalid metadata, controller points at unknown node BrokerId(-1)

While the consumer is connected it generates this warning fairly regularly in the shotover node it's connected to:

the messages do get published and are able to be consumed though from what i can see
