* Adding a way to inject a request ID It is very useful to associate a request ID to each incoming request, this change allows to provide a function to do that via Server Option. The change comes with a default function which will generate a new request ID. The request ID is put in the request context along with a common logger which always logs the request-id We add gRPC interceptors to the server so it can get the request ID out of the gRPC metadata and put it in the common logger stored in the context so as all the log lines using the common logger from the context will have the request ID logged
