I think having a `@ProgressReporter` could be an elegant way to allow users
to plug in additional functionality. Progress could be just the first thing a
task could expose, and in the future if we think of others, we just need to add
a new annotation.

> Add a getProgress to the Task interface, this is very helpful for long
> running tasks, from which we know the status of a task and see if it's
> blocked. The return value is a double, ranging from 0 to 1.0, 1.0 indicates a
> task is finished
