(I) Experiment of the necessity of TimeseriesMetadata

- Although the index area structure with no TimeseriesMetadata speeds up a little in raw data query,
it reduces the speed a lot in aggregation query. => We should reserve TimeseriesMetadata. - The time cost does not change in the data area of TsFile.
(II) Experiment about combine Chunk and Page

...
- one level index in one TsFile.
- Suitable for small Chunk (Mass Timeseries) scenario, in which 1 chunk has only 1~2 pages
(Note: Since 0.12, If one Chunk has only one Page, then PageStatistics will be removed, we only store statistics in ChunkMetadata)
(III) Experiment about how to store PageHeader
