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.
