Add worker pool to the listener to prevent blocking. It is used only for
notary notifications and new block events handling since it uses RPC
calls. That may lead to the deadlock state: neo-go cannot send RPC until
notification channel is read but notification channel cannot be read since
neo-go client cannot send RPC.

Provide current heights as an argument to ticker.
Zero height disables any checks, thus corresponding to the old
behaviour. If non-zero height is used, ignore the tick if the height
is less than the timer tick state.

When IR node configured without main chain, both
`morphListener` and `mainnetListener` are pointing
into single listener component. We should not call
`Stop()` twice, because it may trigger channel
closing in neo-go or other components and it
can throw panic.

If mainchain is disabled in IR config then the node should read inner
ring list via role management contract.
Use `NeoFSAlphabetList` method of morph client as IR lister if
`withoutMainNet` flag is set in IR app.

In notary disabled environment, approval of container creation with nice
name attribute takes much more additional GAS than other operations
(due to NNS invocation).
Morph library changes:
* add the ability to specify per-op fees using `StaticClient` options;
* add the ability to customize fee for `Put` operation with named
container in container morph client.
Inner Ring changes:
* add `fee.named_container_register` config value which specifies
additional GAS fee for the approvals of the named container
registrations;
* pass the config value to `WithCustomFeeForNamedPut` option of
container morph client.

Define notification events, implement parsers. Add morph client of
Subnet contract. Listen, verify and approve events in Inner Ring app.

Add hash of the TX that generated notification
to neofs/netmap event structures. Adapt all
neofs/netmap wrapper calls to new structures.

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.

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.

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.
