Roman Leventov 3ae563263a Renamed 'Generic Column' -> 'Numeric Column'; Fixed a few resource leaks in processing; misc refinements (#5957) ... This PR accumulates many refactorings and small improvements that I did while preparing the next change set of https://github.com/druid-io/druid/projects/2. I finally decided to make them a separate PR to minimize the volume of the main PR. Some of the changes: - Renamed confusing "Generic Column" term to "Numeric Column" (what it actually implies) in many class names. - Generified `ComplexMetricExtractor`		2018-10-02 14:50:22 -03:00
