Several reports exist (both with device plugins and CSI) that
kubelet w/ grpc-go sends invalid Authority header and some non
grpc-go servers reject these unix domain socket client connections.
grpc-go sets the Authority header correct when the dial address
is in a format where the its address scheme can be determined.
Instead of making changes to get the all server addresses to unix://
prefixed format, set grpc.WithAuthority("localhost") client connection
override to get the same result.
