SAMZA-2002: SamzaSQL Diagnostics: instrument rest of operators (excep…
…t join & aggregate) and at Query level Second phase of instrumenting SamzaSQL operators to add and maintain metrics. All operators, except join and aggregate, are instrumented to add Processing Time and Input Rate metrics. Whenever output rate could be different (e.g., filter operator) the output rate is also added. At query level, we have Query Latency, and input and output rates. Author: Shenoda Guirguis <sguirguis@linkedin.com> Reviewers: Srinivasulu Punuru <spunuru@linkedin.com>, Aditya Toomula <atoomula@linkedin.com> Closes #831 from shenodaguirguis/addmetrics.3
