Summary:
This pr refactor plan node into plan + operator.
In the previous version in nereids, a plan node consists of children and relational algebra, e.g.
```java
class LogicalJoin extends LogicalBinary {
private Plan left, right;
}
```
This structure above is easy to understand, but it difficult to optimize `Memo.copyIn`: rule generate complete sub-plan,
and Memo must compare the complete sub-plan to distinct GroupExpression and hurt performance.
First, we need change the rule to generate partial sub-plan, and replace some children plan to a placeholder, e.g. LeafOp in Columbia optimizer. And then mark some children in sub-plan to unchanged, and bind the relate group, so don't have to compare and copy some sub-plan if relate group exists.
Second, we need separate the origin `Plan` into `Plan` and `Operator`, which Plan contains children and Operator, and Operator just denote relation relational algebra(no children/ input field). This design make operator and children not affect each other. So plan-group binder can generate placeholder plan(contains relate group) for the sub-query, don't have to generate current plan node case by case because the plan is immutable(means generate a new plan with replace children). And rule implementer can reuse the placeholder to generate partial sub-plan.
Operator and Plan have the similar inheritance structure like below. XxxPlan contains XxxOperator, e.g. LogicalBinary contains a LogicalBinaryOperator.

```
The concrete operator extends the XxxNaryOperator, e.g.
```java
class LogicalJoin extends LogicalBinaryOperator;
class PhysicalProject extends PhysicalUnaryOperator;
class LogicalRelation extends LogicalLeafOperator;
```
So the first example change to this:
```java
class LogicalBinary extends AbstractLogicalPlan implements BinaryPlan {
private Plan left, right;
private LogicalBinaryOperator operator;
}
class LogicalJoin extends LogicalBinaryOperator {}
```
Under such changes, Rule must build the plan and operator as needed, not only the plan like before.
for example: JoinCommutative Rule
```java
public Rule<Plan> build() {
// the plan override function can automatic build plan, according to the Operator's type,
// so return a LogicalBinary(LogicalJoin, Plan, Plan)
return innerLogicalJoin().then(join -> plan(
// operator
new LogicalJoin(join.op.getJoinType().swap(), join.op.getOnClause()),
// children
join.right(),
join.left()
)).toRule(RuleType.LOGICAL_JOIN_COMMUTATIVE);
}

Due to the current architecture, predicate derivation at rewrite cannot satisfy all cases,
because rewrite is performed on first and then where, and when there are subqueries, all cases cannot be derived.
So keep the predicate pushdown method here.
eg.
select * from t1 left join t2 on t1 = t2 where t1 = 1;
InferFiltersRule can't infer t2 = 1, because this is out of specification.
The expression(t2 = 1) can actually be deduced to push it down to the scan node.
Currently, the libhdfs3 library integrated by doris BE does not support accessing the cluster with kerberos authentication
enabled, and found that kerberos-related dependencies(gsasl and krb5) were not added when build libhdfs3.
so, this pr will enable kerberos support and rebuild libhdfs3 with dependencies gsasl and krb5:
- gsasl version: 1.8.0
- krb5 version: 1.19
* [Refactor][Bug-Fix][Load Vec] Refactor code of basescanner and vjson/vparquet/vbroker scanner
1. fix bug of vjson scanner not support `range_from_file_path`
2. fix bug of vjson/vbrocker scanner core dump by src/dest slot nullable is different
3. fix bug of vparquest filter_block reference of column in not 1
4. refactor code to simple all the code
It only changed vectorized load, not original row based load.

Hive and trino/presto would automatically trim the trailing spaces but Doris doesn't.
This would cause different query result with hive.
Add a new session variable "trim_tailing_spaces_for_external_table_query".
If set to true, when reading csv from broker scan node, it will trim the tailing space of the column
