`Inhume` operation can be performed on already deleted objects, and in this
case the entry will be added to the graveyard. `Delete` operation finishes
with error if object is not presented in metabase. However, the entry in the
cemetery must be deleted regardless of the presence of the object.
Additionally, now `Delete` does not return an error in the absence of an
object.

Extra blocks for notary deposit must not be less than extra blocks
at notary tx rounding.
Consider you make notary deposit every 1000 block for next
1100 blocks. At block 555 you made notary deposit up to 1655.
At block 1554 you want to send notary tx. Notary client uses rounding
to calculate `until` value. By default notary client rounds with up
to 150 block ahead, thus for tx at 1554 `until` will be 1700.
1700 is bigger than deposit limit at 1655 and tx will fail. However
if extra blocks for notary deposit will be 200, then this case
won't be possible.

Register reputation service server that:
* verifies signatures of the requests and signs the responses;
* attaches response meta header to the responses;
* logs body structures of the requests (only as initial implementation, in
future it will be replaces with local trust storage).

There are changes in `go mod download` in go1.16 and it
adds checksums for all module contents. Therefore we should
perform `go mod tidy` after `go mod download`.

Hex encoded values are often may be misinterpreted as base58
values. Reverse case is quite rare, so it is better to try
hex decoding first.

everywhere where list of public keys is presented.

This method has been removed from netmap contract. Corresponding
event from neofs contract renamed to AlphabetUpdate and should not
be processed, because alphabet updated from `RoleManagement`
contract.

RoleManagement native contract (ex designate contract) stores list
of keys per role. Main net uses NeoFSAlphabet role to store keys of
alphabet nodes of inner ring. Side chain uses the same role to store
keys of all inner ring nodes, including alphabet.

There is a need to track the results of Object interactions with the remote
peers during node's lifetime. Each successful operation should increment the
number of satisfactory interactions with the remote peer, and the failed
ones, on the contrary, decrement. Collected numbers of satisfactory
interactions are going to be used for calculation of the normalized local
trust values according to original EigenTrust algorithm.
Implement wrapper over local trust storage that calls `Update` method on it
with the result of any object operation. The wrapper provides interface of
the remote client constructor. It is used as a `ClientConstructor` component
in Object service server of the app.

Implement simple `WriterProvider` building a `Writer` that writes incoming
