BlockingTask (Broker - AMQP 1.0.26 API)

```
public interface BlockingTask
```
A task that executes a blocking operation and may throw an exception. Implementors define a single method with no arguments called execute.
The BlockingTask} interface is similar to Runnable, in that both are designed for classes whose instances are potentially executed by another thread. A Runnable, however, does not return a result and cannot throw a checked exception.
