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.

Get innerring list and committee in innerring
indexer from interfaces, not from structs.
Passing IR fetcher to indexer constructor depends
on having Notary contract in sidechain(use NeoFS
role or netmap contract).

Add `IrFetcherWithNotary` and `IrFetcherWithoutNotary`
that can fetch IR keys with and without usage of
notary contract.
Both can be hidden behind
`InnerRingKeys() (keys.PublicKeys, error)` interface.

We should go through every key in main chain list to merget lists
as fast as possible. Previously we drop main chain traversing as
soon as we have no more new keys to add. Instead we should try
to go for old keys in the list and add it as more as we can.

Make `Validator.VerifyAndUpdate` method to return an error if at least one

Session tokens have limited lifetime in NeoFS. Container processor should
verify lifetime of the incoming tokens.
Define `NetworkState` interface with `Epoch` method to get number of the
current epoch. Use Netmap contract client's wrapper as `NetworkState` of
Container `Processor`. Check values of token lifetime, and deny if:
* NBF value is gt the current epoch;
* IAT is gt the current epoch;
* EXP is le the current epoch.
