IMPALA-10648 addendum: Handle null return value from catalog's
renameTable() api
CatalogServiceCatalog.renameTable(oldTable, newTable) api
sometimes return null if oldTable's db does not exist
in cache. The caller of this api should check for null
return value.

> IMPALA-10613 introduced changes to expose table/partition metadata stored in
> catalog cache over HMS APIs.
> In this task, we invalidate the non transactional table from cache if HMS DDL
> apis like create/alter/drop table/partition are accessed from catalogd's
> metastore server. Any subsequent get table request fetches the table from HMS
> and also loads it in cache. This ensures that any get_table/get_partition
> requests after ddl operations on the same table return the most updated table
