Focus aware query polling

[johnnyomair]

Apollo does not support pausing polling when the current browser tab is not in focus (see feature request). Therefore we add our own useFocusAwareQuery hook that wraps useQuery and pauses/resumes polling upon focus/blur.

better would be to avoid wrapping the hook, as you can only wrap once - to get one feature - but not twice. Some HOC system that let's the user do comoposition is a possible solution - but overkill in this case. Some kind of additional hook is nice imho (downside: not so easy to use as yours)

possible alternative: comet-admin has it's own useQuery with all features we need.

@nsams what would you say to a solution like this?

const { data, startPolling, stopPolling, refetch } = useQuery(...);

useFocusAwarePolling({ pollInterval: 10000, startPolling, stopPolling, refetch });

👍

(not so easy to use, but still preferable for the aforementioned reason)

Done in ac42702. Also added docs on how to use.
