Add selected engine name to QueryAPI.update_cache arguments

[fubuloubu]

Overview

It sometimes might be helpful for profiling purposes for a service using an external plugin to have access to what plugin was chosen to provide the result of a data query. In this way, the service might be able to make future decisions on what or how to organize data in order to provide those types of requests more quickly in the future. For example, perhaps the Kerkopes plugin could collect metadata on a query so that it will reorder data available in intermediate cache for quicker response times. This type of data collection should always be optional (I think opt-out is reasonable), but I think it could dramatically improve the QoS that a plugin user might see in certain cases.

Specification

Change to:

def update_cache(self, selected_engine: str, query, data)`

Also, reiterate that all calls to this method should never fail so as not to stop the processing loop in QueryManager from functioning correctly, so all errors should be handled and logged if using this feature in this way to communicate to an external API service.
