[#38] Change ObjectID format from UUID to Hash

Browse source 
NeoFS Object are now Content-addressed. It means the Object's address depends on
it's content. ObjectID is now calculated as hash of Header, which contains a
hash of payload. If either if Object's payload of Headers change, the ID will
also change.
