[SPARK-14631][SQL][WIP]drop database cascade should drop functions for
HiveExternalCatalog
## What changes were proposed in this pull request?
as HIVE-12304, drop database cascade of hive did not drop functions as well
(even after the fix, by call `client.dropDatabase` would still not drop
functions). We need to fix this when call `dropDatabase` in
`HiveExternalCatalog`.
