I moved default value from `SimpleStateDescriptor` to
`ValueStateDescriptor`. Now only `ValueStateDescriptor`s have default values.
The serialization methods may contain some duplicated code, but i think it's
acceptable.
I also modify the implementation of `HeapReducingState`s. The first value
will be copied before being put into the heap.
@aljoscha What do you think of these changes?
> Add get() method in State interface
> -----------------------------------

> Key: FLINK-5023
> URL: https://issues.apache.org/jira/browse/FLINK-5023
> Project: Flink
> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Reporter: Xiaogang Shi
> Assignee: Xiaogang Shi
>
> Currently, the only method provided by the State interface is `clear()`. I
> think we should provide another method called `get()` to return the
> structured value (e.g., value, list, or map) under the current key.
> In fact, the functionality of `get()` has already been implemented in all
> types of states: e.g., `value()` in ValueState and `get()` in ListState. The
> modification to the interface can better abstract these states.
