According to https://pkg.go.dev/context#pkg-variables, ContextCancelled
should be returned when the context is canceled for some reason other
than its deadline passing. So creating gRPC stream with dial timeout fits
better for context.DeadlineExceeded.

* `c.conn` may be already invalidated but the rpc client can't detect this.
`NewStream` may hang trying to open a stream with invalidated connection.
Using timer with `dialTimeout` for `NewStream` fixes this problem.
