    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
