In previous implementation IR handler of `AddPeer` notification didn't send
registration to contract if existing peer changed has changed its
information. as a consequence, the network map members could not update the
information without going into offline.
Change `processAddPeer` handler to check if
* candidate in the network map is a brand new
* or information about the network map member was changed
and call `AddPeer` method if so.

Timer is not suitable for notary deposits because it can never fire
in case of desynchronization or external epoch changes. Notary deposits
must be handled on new epoch event.

IR tries to keep 1:3 proportion of GAS and
notary balances respectively. If that proportion
has been messed(means that notary balance is
lower than required) it sends half of its
GAS balance to the notary service.

After recent changes morph client wrappers provide contract address getter.
It can be used to compose notification parsers and handlers.
Use `ContractAddress` method in constructors of notification parsers and
handlers. Remove no longer used script hash parameters of event processors.

Make `Validator.VerifyAndUpdate` method to return an error if at least one
of LOCODE-derived attributes is set explicitly. Thus, IR will not confirm
the candidates for the network map who independently set these attributes.
Cover `Validator.VerifyAndUpdate` method with unit tests.

Processors that use `invoke` package to make chain invocation should provide
fee config and client with enabled or disabled notary support. If notary
support is disabled, then functions from `invoke` package will perform
ordinary method invocation with extra fee.
Processors that use `morph/client` wrappers should check `notaryDisabled`
flag to call corresponding wrapper function.
Netmap processor omits some actions during validator syncronization
if notary is disabled.

Previously UN-LOCODE attribute was required for each network map candidate.
In the absence of this attribute, the candidate was not allowed into the
network map. After revising the requirements for candidates, it was decided
not to require the mandatory installation of the attribute by candidates.
From now inner ring does not modify location attributes of the network map
candidate in the absence of UN-LOCODE attribute and does not block entry
into the network map for this criterion.

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.

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.

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.

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.
