This PR:
- Add a new implemention of `DeleteBuffer`: listDeleteBuffer
  - holds cacheBlock slice
  - `Put` method append new delete data into last block
  - when a block is full, append a new block into the list
- Add `TryDiscard` method for `DeleteBuffer` interface
  - For doubleCacheBuffer, do nothing
- For listDeleteBuffer, try to evict "old" blocks, which are blocks
before the first block whose start ts is behind provided ts
- Add checkpoint field for `UpdateVersion` sync action, which shall be
