AttemptMetadataKey = "x-retry-attempt" in retry StreamClientInterceptor

[Boklazhenko]

Hi, Is it possible add AttemptMetadataKey = "x-retry-attempt"
https://github.com/grpc-ecosystem/go-grpc-middleware/blob/main/interceptors/retry/retry.go#L22

in StreamClientInterceptor ?

exactly the same way it works in UnaryClientInterceptor

thank you

Seems like it might be possible to just add it to the context of the streaming call. Would you like to contribute this fix?

[Boklazhenko]

yes, i can try that later
