Kirill Tkalenko updated IGNITE-17230:
-------------------------------------
    Description: 
*Notes*
Description may not be complete.

*Goal*
To implement the new checkpoint (described in IGNITE-15818), we need to modify  
*FilePageStore*. 
A list (in reverse order) of *DelataFilePageStore* will be added to its 
structure, which will increase after each checkpoint (at its completion) and 
decrease after each merge with the *FilePageStore* by "compacter".

*DelataFilePageStore* will contain:
* Sorted list of *pageId*s: allows by binary search to find the offset in this 
file for the requested *pageId*;
* Allocation Index: *pageId* of the last allocated page;
* Pages themselves are sorted by *pageId*.
