This pattern is -- if requested (by test) suspend code execution until requestor (the test) explicitly wakes it up. For that the injected place should inject a lambda that is called with so called "handler" at hand and try to read message from the handler. In many cases the inner lambda additionally prints a message into logs that tests waits upon to make sure injection was stepped on. In the end of the day this "breakpoint" is injected like
```
co_await inject("foo", [] (auto& handler) {
log.info("foo waiting");
co_await handler.wait_for_message(timeout);
});
```
This PR makes breakpoints shorter and more unified, like this
```
co_await inject("foo", wait_for_message(timeout));
```
where `wait_for_message` is a wrapper structure used to pick new `inject()` overload.
