* Opentracing survival guide * Update decorator names in doc * Doc cleanup These are all alterations as a result of comments in #5703, it includes mostly typos and clarifications. The most interesting changes are: - Split developer and user docs into two sections - Add a high level description of OpenTracing * newsfile * Move contributer specific info to docstring. * Sample config. * Trailing whitespace. * Update 5703.misc * Apply suggestions from code review Mostly just rewording parts of the docs for clarity.
