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.

All client wrappers should use underlying static client with enabled notary

Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
Some of the client wrapper's methods should produce notary contract's
invocations. In previous implementation all wrappers provided separate
methods to do it. Since notary and non-notary invocation scenarios have very
different goals, it makes sense to separate the scenarios of using the
client wrapper at the stage of its creation.

option which enables tries of the notary invocations on underlying static
client. Mark all notary-dedicated methods as deprecated.

There are two scenarios of invocation of contract methods:
1. do not invoke notary contract;
2. try to invoke notary contract if it is enabled in Client.
Taking this into account, `StaticClient` can work in one of the two described
modes. Based on this, it makes sense at the stage of creating `StaticClient`
to fix the call mode, and the further abstract from it.
Define `StaticClientOption` setters of `StaticClient` optional parameters.
Add `TryNotary` constructor of option which enables notary tries. Call
`NotaryInvoke` on underlying `Client` if the option is provided, otherwise
call `Invoke`. Mark `NotaryInvoke` method of `StaticClient` as deprecated.
