Define a structure for dealing with the geographic location of nodes.
Implement VerifyAndUpdate (with the same purpose as NodeValidator interface)
that checks LOCODE attribute and fills other attributes of the location.
Technically the entity is a wrapper over the NeoFS location database: it
maps the node LOCODE to the database record from which the new attributes
are generated.

Define NodeValidator interface of the entity that checks and finalizes
NodeInfo structure. Add NodeValidator to Netmap processor. Pass NodeInfo
structures of network map candidates to NodeValidator in order to verify it
and prepare to final state required by network.

Check if `new(big.Int)` will be efficient later and replace
all `big.NewInt()` in code or leave it as it is.

TxTable used twice in context to transfer assets to
and from banking account. There is no need to store
instance of table persistently.

Some transfers from container owners into bank account may
fail due to lack of assets, so we have to deal with remaining
amount of assets in banking account.

Basic settlement context is a main structure that
implement logic of basic settlement phases: collecting
assets from container owners and then distributing them
to storage nodes.

There are two notifications:
- start estimation notification produced at the beginning of the
epoch,
- stop estimation notifications should be produced before
basic audit settlement starts.

There is no point of making separate `Fee` and `NoFee`
wrappers because all reading operations are free disregarding
of fee value in static client. However we can use these same
wrappers so send transaction.

event.

Do not pass zero transfers from the calculation table to Exchanger. Revert
transfers with negative amount since Exchanger interface requires positive
amounts of funds.

Move control of the minimum cost of payment for the audit from the
implementation of the Exchanger to the place where the amount is calculated.

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).

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.

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.

Add numeric return from TaskManager.Reset method that shows the number of

Implement Reset method on audit task manager that cleans task queue.
Extended TaskManager interface with Reset method on IR side. Call Reset
method in audit processor before new audit start.

Refactored pkg/netmap package provides JSON converters for
NodeInfo and PlacementPolicy structures, that has been used
by client applications.
It also updates Node structure itself so it is a part of

There is an optimization to send ApprovePeer tx only in
case if `touch` returns false. It returns false if node
is not in the cache or it was flagged to removal.

This event will be produced by new epoch handler. All
cleanups should be synchronous because smart contract can't
store inner ring votes forever. Therefore voting should be done
in similar time interval for all inner ring nodes.

Cleanup table is a cache for inner ring node to look for netmap
snapshot. It updates access time of bootstrapped nodes and will
be used to send `updateState` txs to clean netmap from unresponsive
nodes.
