Do not pass zero transfers from the calculation table to Exchanger. Revert

Calculate payments to storage nodes for the passed audit when changing the
epoch. The calculation results are wrapped in a call to the Balance contract
(one transaction per user-to-user transfer).

Implement component that analyzes audit results and generates transactions
for payment of awards for successfully passed audit. When calculating the
total fee, the declared price of the node (attribute) and the total volume
of storage groups, which were successfully audited by the container, are
taken into account. In one call the calculator processes all audit results
for the previous epoch (relative to the calculated parameter).

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.

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.

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.
