If all seq data, and compaction is well done, we will only need to get one TimeSeriesMetadata to calcuate count for each device. However, according to the profiler result, we found a lot of overhead in SeriesScanUtil, in this pr we will try to save the useless code execution. 1. needless set in initQueryDatasource in some cases 2. save device.toString() if cache hit in TimeSeriesMetadataCache 3. use result of map.get() to judge whether a key exists instead of using map,containsKey before calling map.gett  -- This is an automated message from the Apache Git Service.
