some highlights for those changes.

• Producing the truncateTail implementing in per table in freezer data
• Rename TruncateAncients -> TruncateHead
• Produce storing metadata information per table stored in disk for keeping track of virtualTail, which like soft delete, keeps deleted items in memory, the truncateTail cleaning up will happen in disk with file unit for avoiding reindex logic.
• The truncate logic is complex when it need to update index entries in index file before starting real truncating data files in disk.
• In the next implementing, It will produce the other subfolder for storing ancient
  stateFreezerName = "state" // the folder name of reverse diff ancient store. Which use this truncateTail frequently
