Commit 63bd6a5aec8d712210abf261f2fd98b7a60ce885 in impala's branch

IMPALA-11047 Preconditions.checkNotNull(statsTuple_) fail in HdfsScanNode.java
if PARQUET_READ_STATISTICS=0
This patch addresses the check not-null failure in FE by checking
the query option PARQUET_READ_STATISTICS in the following situations:
1) When determining whether to apply the min/max overlap predicate;
2) When modifying query option minmax_filter_threshold and
minmax_filtering_level for applying min/max filters to sort or
partition columns.
When PARQUET_READ_STATISTICS is true or 1, then either will proceed.
Testing:
1. Add a new test in TestOverlapMinMaxFilters;
2. Ran the core test successfully.

> Project: IMPALA
> Issue Type: Bug
> Affects Versions: Impala 4.0.0
> Reporter: Riza Suminto
> Assignee: Qifan Chen
> Priority: Major
>
> There is a conflict happening in HdfsScanNode.java vs
> RuntimeFilterGenerator.java when initializing overlap predicate.
> In HdfsScanNode.java, computeStatsTupleAndConjuncts that init statsTuple_
> will not be called because PARQUET_READ_STATISTICS=0.
> [https://github.com/apache/impala/blob/9d61bc4/fe/src/main/java/org/apache/impala/planner/HdfsScanNode.java#L409]
>
> On the other hand, in RuntimeFilterGenerator.java, disable_overlap_filter is
> set to false without considering what is the value of PARQUET_READ_STATISTICS.
