Support `errorPolicy` in `useSubscription` hook and `subscribeToMore` function

[jerelmiller]

Subscriptions created via client.subscribe(...) adhere to the errorPolicy passed into its options (#11162). This however is missing currently in useSubscription and subscribeToMore even though they use the same primitive function to kick off the subscription.

To ensure feature parity, errorPolicy should be a supported option in both the useSubscription hook and the subscribeToMore function available on ObservableQuery.

Edit: support for errorPolicy in useSubscription is live with 3.11.

@jerelmiller - Is there still no way to set errorPolicy:'all' in the Apollo Client useSubscription hook? So no way to handle partial successes in subscriptions?

@jhalborg so sorry I missed your comment! I was on vacation the week you tagged me 😅.

#11928 addresses this issue for useSubscription and will release with 3.11.0 so its coming soon!

No worries 😄

Great news, thank you!

Support for errorPolicy in useSubscription is live with 3.11. Please upgrade to that version to get this functionality.

Would you mind to update docs? https://www.apollographql.com/docs/react/data/subscriptions/

errorPolicy (optional) Since 3.11.0

it is confusing now, since I thought it was available in 3.0
