Construct wrapper over the Container contract client with `TryNotary` option

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.
Define `Option` constructor for container client wrapper. Add `TryNotary`
option which enables tries of the notary invocations on underlying static
client. Mark all notary-dedicated methods as deprecated.
Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
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.
