[#211] blobstor: Add a branch for processing objects by size in Put

Browse source 
Implement "big or small" property classifier (only the size of the payload
is temporarily considered). Save "big" objects in shallow dir. Save "small"
objects in shallow dir until the moment of implementation of blobovnicza.
