OutlierDetection does not provide a Status description when ejecting #10673
Description
Although RPCs should not fail because of OutlierDetection, as it makes sure there are still some working addresses, passing down a Status without a description can make debugging hard:
grpc-java/util/src/main/java/io/grpc/util/OutlierDetectionLoadBalancer.java
Lines 328 to 329 in bdb0c72
A hard-coded description would be really easy and make things more clear.
