Review comment:
       Could be please use underscores to separate names? I understand that the 
ones before and after are not using them, but currently the underscore is the 
"standard"

> Add a config param "hive.default.storage.handler.class" so we can set a 
> default storage handler class that can be used for all create table 
> statements. By default it would be an empty string, taking no effect.
> This would allow existing user queries to be reused for a new table format 
> for example, such as Iceberg. 
> For example, after setting in the config: hive.default.storage.handler.class= 
> org.apache.iceberg.mr.hive.HiveIcebergStorageHandler
> The query: CREATE TABLE abc (a int, b string) LOCATION ...
> would be equivalent to: CREATE TABLE abc (a int, b string) STORED BY 
> 'org.apache.iceberg.mr.hive.HiveIcebergStorageHandler' LOCATION ...
