Default ObjectNameFunc for all REST Stores

All `Store`s in Kubernetes follow the same logic for determining the name of an object.  This change makes it so that `CompleteWithOptions` defaults the `ObjectNameFunc` if it is not specified.  Thus a user does not need to remember to use `ObjectMeta.Name`.  Using the wrong field as the name can lead to an object which has a name that bypasses normal object name validation.
