[SPARK-14603] [SQL] [WIP] Verification of Metadata Operations by Session
Catalog
#### What changes were proposed in this pull request?
Since we cannot really trust if the underlying external catalog can throw
exceptions when there is an invalid metadata operation, let's do it in
SessionCatalog.
- [X] The first step is to unify the error messages issued in Hive-specific
Session Catalog and general Session Catalog.
- [ ] The second step is to verify the inputs of metadata operations.
#### How was this patch tested?
Todo: add test cases and verify the error messages we issued
