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.

The client needs of the IR application are very limited and rarely change.
Interface changes of the client library should not affect the operation of
various application packages, if they do not change their requirements for
the provided functionality. To localize the use of the base client and
facilitate further support, an auxiliary package is implemented that will
only be used by the IR application.

Add name and zone arguments to `Put` method of wrapper over the Container
contract client. Pass result of `container.GetNativeNameWithZone` function
to the method in `Put` helper function. Due to this, the storage node will
call the method depending on the presence of the container name in the
attributes.
Make IR to listen `putNamed` notification event. The event is processed like
`put` event, but with sanity check of the container attributes.

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.

There is a need to have the ability to expand the data needed for client
construction.
Replace `network.AddressGroup` parameter of client cache interfaces with
`client.NodeInfo`.

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.

Implement `NotaryContractProcessor` by IR
container processor. Add support for notary
`put` container operation. Do not parse `put`
non-notary notifications in notary enabled
environment.

Prepare all listening structures for notary events:
rename(add prefix/suffix 'notification') all
notification specific handlers/parsers.

IDs come from NeoFS contract in big endian, but it is customary to write in
the node logs in little endian.

There is a need to work with a set of Neo RPC nodes in order not to depend
on the failure of some nodes while others are active.
Support "multi-client" mode of morph `Client` entity. If instance is not
"multi-client", it works as before. Constructor `New` creates multi-client,
and each method performs iterating over the fixed set of endpoints until
success. Opened client connections are cached (without eviction for now).
Storage (as earlier) and IR (from now) nodes can be configured with multiple
Neo endpoints. As above, `New` creates multi-client instance, so we don't
need initialization changes on app-side.
`Wait` and `GetDesignateHash` methods of `Client` return an error from now
to detect connection errors. `NotaryEnabled` method is removed as unused.

Do not read `without_notary` config value from env.
Make morph client constructor return client without
notary support. Enabling notary support should be done
with public `EnableNotarySupport` method separately.
Notary availability is deducted with client. Further,
if notary is presented on chain its support is
enabled at the corresponding client.

When Inner Ring node starts, it should sync nearest epoch tick
event based on the block of the latest epoch. Otherwise epoch
ticking can be stopped, because ballots or notary transactions
are valid for limited period of time.
