IMPALA-11023: Raise error when delete file is found in an Iceberg table
Iceberg V2 DeleteFiles are skipped during scans and the whole content of
the DataFiles are returned. This commit adds an extra check to prevent
scanning tables that have delete files to avoid unexpected results till
merge on read is supported. Metadata operations are allowed on tables
with delete files.
Testing:
- Added e2e test.
