CheckIn:Fix bugzilla bug 177870 Allow design-time data set cache to be controlled solely by AppContext in 2.1.3 and head

- Bugzilla Bug (s) Resolved:
[177870] Allow design-time data set cache to be controlled solely by AppContext in 2.1.3 and head

 

- Description:
 

Add a new API in DataEngine IResultMetaData getCachedDataSetMetaData, which is behavior as followed:

 

1. This method will return NULL if the named data set is not cached.

2. Otherwise, it will return an IResultMetaData instance which provides at least the ColumnName

                and ColumnType information for all cached columns.

            3. The parameter info is usually important in the acquire of data set result, but it has nothing to do with the meta, so we do not accept it as part of interface declaration.

 

The test case is added as well.

- Tests Description:
Unit Test.
