This is useful when you're using a label to determine the receiver but want to override other options such as `group_by`. Currently you'd have to duplicate the matchers for the receivers to be able to do this. `checkReceiver()` now returns no error if a receiver is empty and we add a check to ensure that the root route has a receiver defined. I've added a test for this. This brings the `receiver` option into line with the other options (`group_by`, `group_wait`, etc) in the sense that routes can now inherit the receiver from the parent node. From https://prometheus.io/docs/alerting/configuration/: > A route block defines a node in a routing tree and its children. Its > optional configuration parameters are inherited from its parent node > if not set.
