The info struct is shared between all these subtests - there's no need to clutter up each test by redefining it. Signed-off-by: Akshay Shah <akshay@akshayshah.org>
The streaming interceptor should match the behavior of the unary interceptor and gracefully handle non-protobuf messages. Signed-off-by: Akshay Shah <akshay@akshayshah.org>
Amend the unary and streaming interceptors to send validation errors to the client as an error detail. This allows client code to easily parse and work with the structured validation information: for example, a UI might want to display validation errors next to the relevant fields in a form.

Thanks for the quick review, @johanbrandhorst! I also noticed another bug in the streaming interceptor, but I'll fix that in a separate PR. |

This PR improves the protovalidate middleware:
when message validation fails. This allows clients to know which field(s) of
the request were invalid and which validation rules failed.
Speaking as one of the protovalidate authors, we intended validation errors to
be used as gRPC error details. I didn't notice that we weren't sending them
over the wire when I first reviewed this code.
