Most of the time people are interested in successful executions. Unfortunately,
unwrap package can't help here because of a different result structure (some
interface abstract can help, but it's still mostly stack-oriented and sessions
can be a problem), so this additional interface is needed.

Adjust names of all used structures, no need to duplicate `Waiter` everywhere,
we already in the `waiter` package. Also, adjust comments to Actor so that links
to Waiter are properly described in docs.

There are use-cases when not only Actor, but also Invoker and even
simple RPC client must wait (e.g. sendtx or dumptx CLI commands). Actor
requires optional signers in constructor, and it's not always
appropriate to create Actor only to be able to use Waiter, sometimes
it's needed to use only Waiter without Actor.
