Add retryOnWindowFocus

[JoffrayBillon]

I don't know if it's a bug, an inconsistency or just a feature request but the params retryOnWindowFocus doesn't exist as the refetchOnWindowFocus is.

So the api behaves like retry again at each new windowFocus even with a retry at 0.

I know there is many case where the api send 404 and it's good for the app to retry when the data exist but there is also case where it's just a bad request and better not spam the api anymore.

So why not let to the developers the opportunity decide how the api should behaves ?
