This adds a unique ID to every cherrypy request and adds it to the all of the log lines in the web server. Some requests produce multiple log entries, and this will allow us to associate them with each other as well as the cherrpy access log which is emitted at the end of the request. To add this to cherrypy's request logging, we subclass the cherrypy LogManager class and add accessor methods so that whenever the superclass requests a logger, it gets our annotated logger. See: https://github.com/cherrypy/cherrypy/blob/main/cherrypy/_cplogging.py There is an underscore in that module name, but several parts of the cherrpy documentation suggest importing underscore modules for the purpose of extending cherrpy. On the ZuulApi class, we add a similar accessor method for obtaining the annotated logger for any request. The two log streaming classes initialize their log attribute in the constructor since their instances are dedicated to a single request. The remaining classes retain the class-level logger since they operate outside of the request context. Change-Id: I66af717ab34fa4ad3492a01badb25e3865133104
