Some of the client wrapper's methods should produce notary contract's

There are two scenarios of invocation of contract methods:

Alphabet nodes synchronize list of alphabet keys from main chain
`NeoFSAlphabet` role once per epoch. This can lead to a wrong behavior in
single chain deployment (`without_mainnet` config parameter). Alphabet node
in single chain environment will try to get NeoFSAlphabet role from main
chain client, but it'll get result from side chain instead. Side chain
stores list of all inner ring nodes in this role. Therefore it is possible
that alphabet nodes will try to appoint inner ring nodes as alphabet nodes,
which is not correct.
Fix incorrect behavior with disabling of synchronization of alphabet keys in
sidechain-only mode.

Reset. It was caused by tick counter not being reset inside Reset method.

Container listing already supported in the metabase for `engine.List`
operation. To get container statistics engine should provide both the
option to get container volume estimation and list of all containers.

Objects of one container can be split among shards, so engine
should iterate over all available shards to sum all size
estimations.

Storage nodes keep container size estimation so they
can announce this info and hope for some basic income
settlements. This is also useful for monitoring.
Container size does not include non regular or inhumed
object sizes.

multiple times (N times if fractional interval == BASE_INTERVAL / N).

BlockNotifications interface method that returns block channel. Write new
blocks to the channel on notification events with BlockEventID type.

Classifier looks at list of inner ring nodes and container
nodes from current and previous epoch to classify request.
Sometimes these checks might return error.
Consider there is a request from unknown key and container's
placement policy valid for current epoch and invalid for past
epoch. Classifier tries to find if key belongs to container
node from current epoch -- it is not. Then it tries to find if
key belongs to container node from past epoch and it throws
error, because placement policy is invalid for past epoch.
This is a legit case and classifier should ignore such errors
to provide best effort in matching. The only error classifier
should return is an error when request does not contain
public key to classify it.

Pivot used to shuffle nodes in the CRUSH tree. This is
required argument. We use container ID value to select
container nodes, so `nil` value produces incorrect placements.

There is a codecov issue because objects are not placed
in the engine the same way every unit test. Therefore
sometimes there are more coverage, sometimes there are
less. Seeded RNG should solve this issue for engine tests.

Netmap snapshot table caches bootstrap `AddPeer` txs so inner ring
node does not produce redundant approval txs for bootstrapped nodes.
However if node updates states to `Offline`, then such node should
be flagged in snapshot table, so re-bootstrap will actually produce
approval tx.
`ev.PublicKey.String()` returns uncompressed representation of the
node's public key, while snapshot contains compressed values.
Therefore the node was not flagged and re-bootstrap tx was not
approved by inner ring nodes.
