https://godoc.org/google.golang.org/grpc#WithContextDialerhttps://godoc.org/google.golang.org/grpc#WithDialer
grpc/grpc-go#2627
prometheous change:
due to UninstrumentedHandler, being deprecated in the future
empty branch = empty if or else statement
didn't delete them entirely but commented
couldn't find a reason to have them
could not replicate the issue #3406
but if want to keep it commented then we should comment out the if statement as well
