It is possible to provide a timeout to step definitions, however the
semantics are unreliable ( #1506).

```java
@given(value = "^I have (\\d+) cukes in my belly$", timeout = 5000)
public void I_have_cukes_in_my_belly(int cukes) throws Throwable {

}
```

Fixes: #1694

When the step starts a long running task Cucumber will attempt to
interrupt the step once the timeout period is exceeded. If the long
running task ignores the interrupt Cucumber will however not stop the
test. Depending on the context this behavior is either desired or
undesirable. See #1506 for in detail discussion.

Additionally the current implementation is complex and has been prone
to failures (#1244, #1241, #811, #639, #540).

While it is possible to implement different strategies to deal with
timeouts; there is no perfect solution. And regardless of which solution
we pick we would take on a significant amount of complexity. So I
believe that for Cucumber there is no good solution.

However this problem has been solved by various libraries:

 * [JUnit 5 `Assertions.assertTimeout*`](https://junit.org/junit5/docs/5.0.1/api/org/junit/jupiter/api/Assertions.html#assertTimeout-java.time.Duration-org.junit.jupiter.api.function.Executable-)
 * [Awaitility](https://github.com/awaitility/awaitility)
 * [Guava `TimeLimiter`](https://github.com/google/guava/blob/master/guava/src/com/google/common/util/concurrent/TimeLimiter.java)

So rather then keeping a poor feature alive we should recommend users
to migrate to third party solutions.

Remove the eldritch horror that is `Invoker/Timeout.timeout`. While this
could have been done in v4.x, v5 will use Java 8 and most of the above
libraries require Java 8.
