fix(tests): Fix logging integration test

[enochtangg]

Small fix for improving logging in the integration test. Instead of dumping all consumer logs (GHA refuses to print all logs), when an error log is seen, capture 10 lines before and after the error and print to stdout.

Also I'm seeing more of

ERROR taskbroker: Task grpc_server failed: GRPC server task failed: tonic::transport::Error(Transport, Os { code: 98, kind: AddrInUse, message: "Address already in use" })

Which really sucks

I wonder if we're not releasing the ports that grpc is connected to quickly enough?
