NATS publisher context

[l-vitaly]

Hello!

In this place https://github.com/go-kit/kit/blob/master/transport/nats/publisher.go#L67

there is a string: ctx, cancel := context.WithTimeout(context.Background(), p.timeout)

apparently there is an error and need:

ctx, cancel := context.WithTimeout(ctx, p.timeout)

?

Probably, yep.
