Add option for annotating pipeline plug function calls with OpenCensu…

…s spans

Once a Plug pipeline gets long enough and/or executes slowly enough,
a person begins to wonder, "What plug functions are taking so much
time?"  This patch helps answer that question by adding an option
to add OpenCensus span annotations to all plug function executions
in a pipeline.  The new OpenCensus spans can tell you the names of
each pipeline function executed and how much time elapsed in each
span.  Nested pipelines are fully supported.
