[#26] object: Replace CreationPoint with Epoch

Browse source 
In previous version of the format Object message included moment of creation
in two epoch times: NeoFS and Unix. Since unix  is not processed in the
system, this commit narrows the time point of object creation to the system
epoch number. The object.CreationPoint message has therefore been deleted
as no longer used
