PS3, Line 575: as of now();
This doesn't exercise the old partition specs and dropped columns. We can refer 
to the first snapshot if we create the table in the python test, then pass the 
snapshot id as an env_var to run_test_case().

E.g. see: 
https://github.com/apache/impala/blob/d6638f0d9ea2b66f18cbf76e3c25c59026b9851d/tests/query_test/test_iceberg.py#L1707
