["Jianqiang Luo" <jluo@xxxxxxxxxxx>]

- Summary:
Add CACHE option in DataEngineContext, and change DataSetManager to make design-time cache easy to use.

- Bugzilla Bug (s) Resolved:
N/A

- Description:
Now DtE support a global option applied to an instance of data engine. This cache option will affect all query executed in this instance and will override the cache property of data set and application context. There are three possible values:

CACHE_USE_DEFAULT, CACHE_USE_DISABLE, CACHE_USE_ALWAYS. Detailed explanation can be known from DataEngineContext class.

 

Meantime, several methods are added in DataSetManager for making the DtE cache easy to use. The main methods are to retrieve the metadata of data set and the data of data set.

- Tests Description:
Junit test
