- Add GlobalResync(cache.SharedInformer) method to *controller.Impl
- Move UntypedStore from serving/pkg/config to pkg/configmap
- Add onAfterStore callbacks to UntypedStore
- Add TypeFilter to enable composable construction of such callbacks
* Address review
- Unit test GlobalResync()
- Reimpl GlobalResync() using ListKeys()
* Update comments
* Add test for onAfterStore
* Update godoc comment for Logger
* Few changes to the configmap package
- New* methods return concrete types
- defaultImpl is now InformedWatcher
- fixedImpl is now StaticWatcher
- Included a new ManualWatcher that mimics the InformedWatcher
