All node info attribute transformations can't guarantee
the order of attributes. However it should be consistent
otherwise smart-contract won't be able to collect signatures
and approve transaction.

Node info validator may change node attributes, e.g. update
it with human-readable location attributes based on LOCODE.
So inner ring node should provide new node info binary to
smart contract.

Inner ring Server does not modify LOCODE database (Put method), thus it is
better to open it in RO mode.

Implement DB interface required by LOCODE validator on new wrapper over the
LOCODE Bolt DB (Record on new wrapper over LOCODE Bolt DB entries).
Construct LOCODE validator and pass it to Netmap processor's constructor as
NodeValidator parameter.
Thus, candidates for a network map must set LOCODE attribute for which there
is an entry in the NeoFS location database.

Keep list of functions which are called first when the server starts (method
Server.Start). If any of the starters returns an error, the server will not
start. Such starters will mainly be used for resources that need to be
initialized after a successful server construction, but before its main work
(e.g. local files).
Keep list of functions which are called when the server stops (Server.Stop
method). Such closers will mainly be used for resources that need to be
released after server shutdown (e.g. initialized by starters).

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.

Some transfers from container owners into bank account may

There are two notifications:
- start estimation notification produced at the beginning of the

- stop estimation notifications should be produced before

This small refactoring adds `blocktimer.go` file with
all timer related function and constructors. This way
we can create all timers in one place (at the end of
innerring.Server constructor).
To do that we had to move timer reset into global
server state so it can be accessed by netmap
processor.

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.

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).

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.
