In previous version of the format storage group information was stored in
completely in the dedicated header field. However, having a header field
instead of storing it in a payload is not justified, since it is used only
to check the presence in the object. Based on this, this commit defines a
message for marking the object as the custodian of information about the
storage group and changes the type of field StorageGroup to it. Information
about the storage group will be stored serialized in the payload of the
objects marked in this way

In previous version of the format storage group lifetime was measured in two
epoch times: NeoFS and Unix. Since unix is not processed in the system,
this commit narrows the time point of storage group expiration to the
system epoch number. The storagegroup.StorageGroup.Lifetime message has
therefore been deleted as no longer used.

In the previous format, the object header was subdivided into system and
extended parts, which confused the purpose of these parts. In particular,
the extended header contains system fields. To clarify the non-intersection
of the mentioned parts of the object header, it was decided to rename System
to Main.

This commit replaces PayloadChecksum field from ExtendedHeader to
IntegrityHeader for assembling all verification data in one structure.

This commit moves the public key of the creator of the object to
IntegrityHeader to encapsulate the verification data in one message. Thus
field PublicKey of message Header has been moved to message IntegrityHeader
with the name CreatorKey. As a result, PublicKey message is deleted as no
longer used.

Redirect field was introduced for the future, however, at the moment it is
not used anywhere. This commit removes field Redirect from ExtendedHeader
message. It can be added back later without losing API backward
compatibility.

In previous version of the format ExtendedHeader consisted of one field
Value, defined by oneof mechanism. Such a definition format give complete
freedom when composing an object header, however, it did not allow strictly
structuring the header format at the level of type syntax. Since the object
has a well-defined structure in the system, this commit replaces the
definition through oneof with a set of fields. As a consequence, storing a
set of extended headers of the new type in the general header became
redundant, so the repeated keyword was removed.

This commit replaces Transform message with SplitHeader in oneof definition
of Value field of Header message. The latter, unlike the first, carries
complete information about the generation of the object by splitting the
payload. As a result, the message is deleted as no longer used.

This commit defines SplitHeader message that encapsulates data about
spawning the object through a payload splitting. Message fields contain
information about the hierarchy in the split-chain as well as information
about the origin object.

This commit makes ObjectID field of refs.Address message to use dedicated
message for object identifier ObjectID.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
This commit defines ObjectID message in refs package. In the future, this
structure can be ported into messages in place of the object identifier
field to maintain format uniformity. Also, storing the identifier in a
dedicated message will allow, if necessary, to expand it with additional
information without losing backward compatibility within one version of the
API.

This commit merges object system header fields ID and CID into field Address
of type refs.Address. This will allow you to reuse an already existing type
of object reference without duplication and simplify taking the address

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

In previous version of the format Object message included two header fields:
SystemHeader and list of ExtendedHeader. Due to the fact that all headers
were not encapsulated in a single message, some messages were forced to use
Object to convey the full header of the object (e.g. object.HeadResponse).
To resolve this semantic inconsistency, this commit defines a Header
message, consisting of a system and an extended portion. As a result, the
Object now consists of two fields - Header and Payload.

The naming Header obscures its semantic meaning precisely as a subclass of
the general object header. To clarify the layers of typing object headers,
this commit renames the message to ExtendedHeader. As a result, the Headers
field in the Object has been renamed to ExtendedHeaders.

The name of object.UserHeader message implies its use by the user. However,
the attributes of an object can also be set internally by the system. To

Attribute (like container.Attribute).
