row numbers miscounting because of race condition, will cause load to
fail sometimes with warning 'the rows number written doesn't match'.

update Project#findProject
agg function's children could be any expression rather than only slot.
we use Project#findProject to process them. But this util could only
process slot. This PR update this util to let it could process all type
expression.
1. Fix memory issues in LoadStreamMgrTest.
2. Skip S3FileWriterTest by default because it depends on the environment in teamcity.
3. Fix VTimestampFunctionsTest.convert_tz_test.
When a Unique key table carries the `enable_unique_key_merge_on_write` attribute, the value of the agg type is none. Therefore, when doing sparkload, we need to specify the agg type as `REPLACE`.
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
tc/jemalloc_free_memory in web beip:8040/mem_tracker is the cache size of Jemalloc.
Previously lg_tcache_max:20, this will cache up to 1M Bin in the thread cache, which will cause the Jemalloc cache to be too large in some scenarios.
Restore the default lg_tcache_max:16, which can cache a maximum of 64K Bins.
If you are doing a performance POC, you can consider increasing it.
some time extract function changed return type in the previous PR #18369
but it is not change FE constant folding function signature.
This is let them have same signature to avoid BE core.
we use a map to record rewrite cte children result to avoid rewrite
twice in cost based rewritter. However, we record cte outer and
inner in one map, and use null as outer result's key, use cte id as
inner result's key. This is wrong, because every anchor has an outer,
and we could only record one outer. So when we use the cache in cost
based rewritter, we get wrong outer plan from the cache. Then the error
will be thrown as below:
