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.

Zero height disables any checks, thus corresponding to the old

After `Listen` has raw receiver and calls `listen` which has pointer
receiver, leading to ineffectual assign to `started` field.

In some places we panic, in some we return error, in some (audit) just return a client.
However in all of the places static client is created immediately before
the sugared-client creation.
This commit makes all constructors to just return a client for the sake
of code simplification and unification.

It is much more convenient to skip source creation.
Also fix some bugs:
1. `cryptoSource.Int63()` now returns number in [0, 1<<63) as required
by `rand.Source` interface.
2. Replace `cryptoSource.Uint63()` with `cryptoSource.Uint64` to allow
generate uint64 numbers directly (see rand.Source64 docs).

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.

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.
