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.

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

* NBF value is gt the current epoch;
* IAT is gt the current epoch;
* EXP is le the current epoch.

Alphabet nodes synchronize list of alphabet keys from main chain
`NeoFSAlphabet` role once per epoch. This can lead to a wrong behavior in
single chain deployment (`without_mainnet` config parameter). Alphabet node
in single chain environment will try to get NeoFSAlphabet role from main
chain client, but it'll get result from side chain instead. Side chain
stores list of all inner ring nodes in this role. Therefore it is possible
that alphabet nodes will try to appoint inner ring nodes as alphabet nodes,
which is not correct.
Fix incorrect behavior with disabling of synchronization of alphabet keys in
sidechain-only mode.

Extra blocks for notary deposit must not be less than extra blocks
at notary tx rounding.
Consider you make notary deposit every 1000 block for next
1100 blocks. At block 555 you made notary deposit up to 1655.
At block 1554 you want to send notary tx. Notary client uses rounding
to calculate `until` value. By default notary client rounds with up
to 150 block ahead, thus for tx at 1554 `until` will be 1700.
1700 is bigger than deposit limit at 1655 and tx will fail. However
if extra blocks for notary deposit will be 200, then this case
won't be possible.

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).
