Add a generic handler that adds a new tracing context to the request if tracing is enabled. Other handlers are free to modify the tracing context to update information on the fly, such as, func name, enable body logging etc.. With this commit, requests like this ``` curl -H "Host: ::1:3000" http://localhost:9000/ ``` will be traced as well.
