Allow persistent observers to define packages they care about
If a persistent observer does not explicitly declare
that Package Watchdog should watch a package, it may
still start observing a failing package. Add a
method to the PackageHealthObserver interface that
allows an observer to define the conditions for which
it will start observing a package.
Test: n/a since no observers are currently persistent,
current test pass
