IMPALA-6625: Skip computing parquet conjuncts for non-Parquet scans
This change ensures that the planner computes parquet conjuncts
only when for scans containing parquet files. Additionally, it
also handles PARQUET_DICTIONARY_FILTERING and
PARQUET_READ_STATISTICS query options in the planner.
Testing was carried out independently on parquet and non-parquet
scans:
1. Parquet scans were tested via the existing parquet-filtering
planner test. Additionally, a new test
[parquet-filtering-disabled] was added to ensure that the
explain plan generated skips parquet predicates based on the
query options.
2. Non-parquet scans were tested manually to ensure that the
functions to compute parquet conjucts were not invoked.
Additional test cases were added to the parquet-filtering
planner test to scan non parquet tables and ensure that the
plans do not contain conjuncts based on parquet statistics.
3. A parquet partition was added to the alltypesmixedformat
table in the functional database. Planner tests were added
to ensure that Parquet conjuncts are constructed only when
the Parquet partition is included in the query.
