[HIVE-18707] Dropping database via HiveMetastoreClient involves useless work

Description

HiveMetastoreClient has dropDatabase() method which does this:

 

if (cascade) {
   List<String> tableList = getAllTables(name);
   for (String table : tableList) {
     try {
       // Subclasses can override this step (for example, for temporary tables)
       dropTable(name, table, deleteData, true);
     } catch (UnsupportedOperationException e) {
       // Ignore Index tables, those will be dropped with parent tables
     }
    }
}

This isn't needed since the similar thing is done on the server side and just wastes time in sending multiple server calls.
