------------------------------------------------------------------
[~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.
