`Batch` can execute the function multiple times leading to multiple
increases of a size approximation.

The buffer size value is somewhat arbitrary and making in configurable
doesn't make much sense, given that we can't really restrict total resource
consumption in other places. `Copy` uses 32 KiB buffer by default, which
is not big. This approach is also more flexible as we can get rid of
buffer completely by implementing `ReaderFrom`, `WriterTo` interfaces.

GracefulStop() may be blocked until all server-side streams
are finished. There is no control over such streams yet, so
application may be frozen in shutdown stage.
Naive solution is to add timeout for GracefulStop(). At this
point healthy connection will be finished and unhealthy
connections will be terminated by Stop().

Alphabet nodes in notary enabled environment cannot call `UpdateState`
method to remove unwanted storage nodes from the network map,
because this method checks witness of the storage node.
To force storage node state update, alphabet nodes should invoke
new method `UpdateStateIR` which is similar to `AddPeerIR`.
State update initiated by the storage node itself is processed
the same way as before -- alphabet nods resign such transaction.

`Register` was renamed to `AddPeerIR` for consistency with
`UpdateState` changes in
https://github.com/nspcc-dev/neofs-contract/pull/227
This is protocol breaking change for notary enabled environment.
Luckily, there is no notary enabled environments anywhere except
of neofs-dev-env, so we can do such thing. We should avoid such
changes in the future, though.

`apistatus` package provides types which implement build-in `error`
interface. Add `error of type` pattern when documenting these errors in
order to clarify how these errors should be handled (e.g. `errors.Is` is
not good).

service. Write reason in format of the errors from the previous
implementation. These errors are returned by storage node's server as
NeoFS API statuses.

Wrap engine with notifications writer (if configured so) to allow sending
notifications right after the object is saved in the local storage.
"Hot" notifications are sent for objects with the following tick epoch
values:
1. 0;
2. *current epoch*.

related to reputation. Make it possible to finish iteration after the
unexpected `NewEpoch` event.
