Add setXxx methods for @Property annotation

We'll be modifying the PropertyConfiguration class so that, instead
of directly setting values in private fields, it will use public
setXxx methods.  Consequently, we have to add the setXxx methods to
the PropertyConfiguration subclasses so that they're available when
the superclass is modified policy/common.
