As part of this change the ReadThroughCache should be made to perform the loading asynchronously, on a separate thread rather than doing it inline on the thread of the caller to acquire.
The asynchronous implementation should add the following methods to the API:
- Future<ValueHandle> acquireAsync(const Key& key)
- ValueHandle acquire(OperationContext* opCtx, const Key& key)
If an invalidate is called for a key, which is being concurrently loaded, it is acceptable to interrupt the loading of the key if it is currently in progress, but the acquire should not fail.
