public static void addPending(Future<?> future)

    Register a pending Future that has a callback.
    
    Parameters:
    
    future - must have at least one callback
  - removePending

public static void removePending(Future<?> future)
```
    Deregister a pending Future that had a callback.
  - completeAllPendingFutures
```
public static void completeAllPendingFutures()
```
    Iterate through all pending futures and get() them, forcing any callbacks to be called. This is used only by the AsyncCacheFilter (if using cache without Objectify) or ObjectifyFilter (if using Objectify normally) because we don't have a proper hook otherwise.
