Summary: This is a complete reworking of the way that Haxl schedules I/O. The main benefits are: * Data fetches are no longer organised into rounds, but can be arbitrarily overlapped with each other and with computation. The scheduler supports an arbitrary queue of work items which it can evaluate while data-fetching is taking place in the background. To take advantage of this, data sources must implement a new form of `PerformFetch`, namely `BackgroundFetch`. The old forms of `PerformFetch` are still supported, but won't benefit from any additional concurrency. * It is now possible to specify on a per-data-source basis whether fetching should be optimised for batching or for latency. A request to a data source that doesn't benefit from batching can be submitted immediately. This is done with the new `schedulerHint` method of `DataSource`.
