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>
