A fully-featured caching GraphQL client.

    // This state value let's us maintain the variables used for the cache key
    // when `skipToken` is used to skip a query after its been executed.
    // Since options aren't provided when using `skipToken`, `variables` would
    // otherwise disappear which means we'd return a new cache key without a
    // variables value which creates a new `ObservableQuery` instance. This was
    // particularly problematic when `refetchQueries` was used because it meant
    // refetching against an `ObservableQuery` instance that had no variables.
