> We have an auto.purge flag, which means skip trash. It can be confusing as we
> have 'external.table.purge'='true' to indicate delete table data when this
> tblproperties is set.
> We should make the meaning clearer by introducing a skip trash alias/option.
> Additionally, we shall add an alias for external.table.purge, and name it
> external.table.autodelete, and document it more prominently, so as to
> maintain backward compatibility, and make the meaning of auto deletion of
> data more obvious.
> The net effect of these 2 changes will be. If the user sets
> 'external.table.autodelete'='true'
> the table data will be removed when table is dropped. and if
> 'skip.trash'='true'
> is set, HMS will not move the table data to trash folder when removing the
> files. This will result in faster removal, especially when underlying FS is
> S3.
