------------------------------------------------------------------

[~DmitriyGovorukhin], please add a comment on why switch segment record should 
be of specific size. Also, should we add a unit-test for serializer and check 
that switch segment is 1 byte exactly? If you think it makes sense, please 
create a separate ticket.
Other changes look good to me.

> We have invariant that switch segment record should have the size of one byte.
> Although, in the current implementation, size calculation with overhard for 
> storing CRC and WAL pointer.
> In current implementation, we can suddenly stop WAL iteration which may 
> result in random data store corruptions or missing updates on node recovery.
