Sorry for the delay. Are there any customers outside the Espresso team? If
we are the only customer right now, it would not be too costly to update the
implementation with the interface. Making the getProgress into the interface
has a good thing that it naturally goes into TaskRunner and we don't need to do
something like "instance of ProgressReportingTask" and then call the
getProgress, or a subclass of TaskRunner which is specific for
ProgressReportingTask and call the getProgress.

> 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
