Motivation: When the child channel initializer fails, or if any part of child channel setup fails, the error that results is not thrown into that child channel but is instead propagated into the server channel. As nothing in grpc was listening for errors there, those errors got lost. This can make some problems particularly tricky to debug, as they lead to silent service failures. Modifications: - Added a channel handler to be put in all server channels. Results: Server channel creation errors now get propagated into the error delegate.
