[SPARK-6034] [SQL] Support Describe Extended (View/DataSourceProvider) in
HiveContext
In HiveContext, describe extended [table | view | cache | datasource table]
is not well supported.
This PR will cover the
```
describe extended [table | view | datasource table]
```
Still, we probably need to refactor the `catalog.lookupRelation()` a little
bit for supporting `describe` the `cached table`
