Jaeger preserves the trace data of router healthz endpoints which is not so helpful for monitoring function metrics and consumes storage to store such trace data. This PR uses `GetStartOptions` to examine the request's path and check if it's a request to healthz endpoint. If yes, skip and not to trace it.
