Issue 2231: Add a --warn=future-deprecated option, along with

FutureDeprecatedWarning and MandatoryDeprecatedWarning subclasses.
Use these to future-deprecate the Taskmaster.Task class, which we intend
to turn into an abstract base class by requiring subclasses to implement
the .needs_execute() method.
