Support to get notdeterministic functions and base tables from plan.
These are implemented by Plan Visitor
**table collect useage example as following:**
```
TableCollectorContext collectorContext =
new PlanVisitors.TableCollectorContext(Sets.newHashSet(TableType.OLAP));
physicalPlan.accept(PlanVisitors.TABLE_COLLECTOR, collectorContext);
```
`collectorContext.getCollectedTables()` has the tables
**nondeterministic functions collect useage example as following:**
```
List<Expression> functionCollectResult = new ArrayList<>();
plan.accept(PlanVisitors.NondeterministicCollector.INSTANCE, collectResult);
```
`functionCollectResult` has the nondeterministic functions
In the past, two conditions needed to be met when sampling a partitioned table: 1. Data is evenly distributed between partitions; 2. Data is evenly distributed between buckets. Finally, the number of sampled rows in each partition and each bucket is the same.
Now, sampling will be proportional to the number of partitioned and bucketed rows.
1. FE could not compile because below error. Intro by PR #25933
```
[INFO] --- exec:3.1.0:java (doc) @ fe-core ---
...
Failed to generate doc for ignoreRuntimeFilterIds
```
2. fix UT bugs intro by below PRs
> - #25951
> - #26031
3. because fe could not compile, FE UT CI do not work well. So, some UT failed be introduced by the PRs merged after PR #25933 merged. So this PR revert them to fix FE UT

The start and end dates of daylight saving time vary depending on the year. Daylight saving time usually starts on the last Sunday in March and ends on the last Sunday in October. During this time, the offset for Europe/London is UTC+1. Outside of daylight saving time, the Europe/London offset is UTC+0.
Doris is not responsible for managing snapshots, but it needs to clear all
snapshots before doing backup/restore regression testing, so a property is
added to indicate that existing snapshots need to be cleared when creating a
repo.
In addition, a regression test case for backup/restore has been added.
in predicate rewrite phase, we eliminate some conjuncts which contains un-interested columns.
for example: T (a, b) partition by (a)
interest cols: a
uninsterest cols: b
for parition prune,
filter "a=1 and a>b" is equivalent to "a=1",
filter "a=1 or a>b" is equivalent to "TRUE"
Follow #25496.
In #25496, I fixed the issue that the aws s3 properties are invalid when passing from FE to BE.
But it missed the `use_path_style` property, which is useful for minio access.
This PR fix it.
Fix select table tablet not effective, table distributed by random.
If tabletID specified in query does not exist in this partition, skip scan partition.
Problem:
When join estimation, upper join output slot statistic ndv would go wrong
Example:
we have two table:
tableA (a1[ndv = 10.0]) tableB(b1[ndv = 0.0], b2[ndv = 10.0])
tableA left join tableB on A.a1 = B.b1. which B.b1 with ndv zero.
the problem is after join estimation, B.b2 changed to 1.0.
Reason:
When estimating outer join, we can assume it behave like inner join. But we estimation then like inner join do
Solved:
When estimation outer join, output slot would update seperatly.
When executing create partitioned table with Nereids, and replication_num property is not set,
the replication number will be 0, so the tablet will has no replica.
For comparison predicate, two arguments must be cast to datetime and push down to storage if either one is date type. This PR disables predicate push-down for this case.
