The problems of the saveAll of input

[babyfish-ct]

In Jimmer, saving entity and saving input are different.

<E> SimpleSaveResult<E> save(E Entity);
<E> SimpleSaveResult<E> save(Input<E> input);

As you see, different input type cause the sample result type. So these method cannot be merged into one, and the first method checks the input argument must not be Input at runtime.

However, for saveAll

<E> BatchSaveResult<E> saveAll(Collection<E> entities);
<E> BatchSaveResult<E> saveAll(Collection<Input<E>> inputs);

will cause compilation error. Be different with languages support real generic type such as C++/C#, Java erase the generic type so both of these two methods have the same signature whose parametere is Collection.

Solution1, don't affect the existing users

<E> BatchSaveResult<E> saveAll(Collection<E> entities);
<E> BatchSaveResult<E> saveAllInputs(Collection<Input<E>> inputs);

Solution2, change the API but affect exsiting users.

<E> BatchSaveResult<E> saveEntities(Collection<E> entities);
<E> BatchSaveResult<E> saveInputs(Collection<Input<E>> inputs);

saveAll保留，但标记 @Deprecated ，以后版本删除。
添加2的实现。
顺便建议记录每个版本破坏性更新的迁移手册（）

Solution2, 变更 API 以保证明确
@deprecated saveAll，0.9 移除
