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.

Alphabet nodes in notary enabled environment cannot call `UpdateState`
method to remove unwanted storage nodes from the network map,
because this method checks witness of the storage node.
To force storage node state update, alphabet nodes should invoke
new method `UpdateStateIR` which is similar to `AddPeerIR`.
State update initiated by the storage node itself is processed
the same way as before -- alphabet nods resign such transaction.

In previous implementation IR incorrectly verified `SetEACL` event of
`Container` contract. The incorrect behavior could be reproduced in two
ways:
1. Create container using session, and perform `SetEACL` operation
with a key that is different from the session one.
2. Create container using session, and perform `SetEACL` w/o a
session, but sign it using session key from the `Put` operation.
The problem was in the `checkSetEACL` validation method of IR container
processor. It always used session token used for container creation
during session ownership check.

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.
