Remote RPC node might be in the transition state and produce
events from the past. We should avoid listening such nodes.
To do that subscriber component can await minimal height of
remote node. If minimal height is not reached, then throw
error.

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

Add `NotarySignAndInvokeTX` method to morph
client. This function allows invoking notary
request with passed main TX(not creating a
new one). It signs passed main TX with
client's key.

Add `NotaryInvokeNotAlpha` to low-level
client. It creates and sends notary request
that must be signed by Alphabet nodes, but
does not sign it by current node's private
key.

Add preparator for notary requests. Is parses
raw notary requests, checks if it should be
handled by Alphabet node. If handling is required,
returns `NotaryEvent` that contains information
about contract scripthash, method name and
arguments of the call.

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

Caching is performed inside `GetNativeContractHash` method of neo-go client,
so the additional cache level is redundant.

There is no need to continue iterating over Neo RPC endpoints in case of
some address-independent error (e.g. NeoFS logic error).
Unwrap and immediately return `neofsError` errors from loop in
`iterateClients`.

Implement `error` interface on new `neofsError` type which is a wrapper over
NeoFS-specific error. Wrap all `Client` errors except neo-go client API ones
into `neofsError`. Wrapped errors are going to be used for multi-endpoint
loop control.

Since morph `Client` works in multi-client mode, there is an error case when
we can not get network magic when all endpoints are unavailable.

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.
