> When creating an Iceberg table, in the MetaHook we currently set external.table.purge=true for all tables, unless provided otherwise.
> This goes against the docs / user expectations: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=82706445#:~:text=When%20dropping%20an%20EXTERNAL%20table%2C%20data%20in%20the%20table%20is%20NOT%20deleted%20from%20the%20file%20system
> As well as this property: hive.external.table.purge.default, which is set to false in the system.
