ARROW-5681: [FlightRPC] Add Flight-specific error APIs This adds a set of exceptions (in Java/Python) and status codes (in C++) for Flight, to convey Flight-specific issues and to let server implementations provide more semantic error messages to clients. The error codes defined are a subset of the gRPC ones. In Flight/Java, you could always raise `io.grpc.StatusRuntimeException` yourself, but we want to abstract away from the gRPC APIs. There are not tests for conveying these statuses cross-language. That should be done as part of ARROW-5875.
