--------------------------------------------------------------
[~cyberdemon], I've left some comments in the upsource review. Please, take a
look.
[~agoncharuk], I have concerns about whether should we add new delta records
for saving rotated ID part; please see my comments in the review. What do you
think?
I also think that we should add new test that covers massive migration of pages
from data to index types and vice versa.

> * We should check reuse bucket first before allocating a new data page
> * MemoryPolicyConfiguration#emptyPagesPoolSize should be removed
