* Add simple probabilistic query tracing and logging for streaming searches ↵Tor Brede Vekterli2019-09-051-0/+15
that time out This currently only catches the cases where a query has not respected its expected timeout and therefore has an actual timeout that is at least a 5x multiple of its expected one. Due to the response payload nature of MessageBus traces it's not given that the trace will contain any information from the backend nodes. But it is highly likely to contain useful information from the client-local policy instances, as well as resending info. To test this very conservatively, only allows approximately 1 query to be traced every 2 seconds and only dumps traces to logs once every 10 seconds.
