Improve invalidation API

Invalidation

Looks like this:

const store = useRemoteData(testPromise.next, { invalidation: InvalidationStrategy.refetchAfterMillis(10) });

Polling

Looks like this

const store = useRemoteData(testPromise.next, {
  invalidation: InvalidationStrategy.pollUntil((x) => x >= 2, 10),
});
