> Extend the StateStore public API and wire through wrapper layers.
> - StateStore.java — add approximateNumUncommittedBytes() default method, isolation-level-related API
> - BatchWritingStore.java — generalize to WriteBatchInterface (supports both WriteBatch and WriteBatchWithIndex)
> - WrappedStateStore.java — delegate approximateNumUncommittedBytes() to inner store
