when using fold constant by be,
the return type of substring('123456',1, 3) would changed to be text, which we want it to be 3 remove windowframe in window expression to avoid folding constant on be

upgrade commons-configuration2 to 2.11.0
upgrade logging-interceptor to 4.12.0
upgrade commons-compress to 1.27.1
upgrade jetty-bom to 9.4.56.v20240826
upgrade azure-sdk to 1.2.27
Iceberg depends on configuration2, and configuration2 relies on a newer
version of commons-lang3. However, there were significant breaking
changes in commons-lang3, which made it
incompatible.https://issues.apache.org/jira/browse/LANG-1705 As a
result, I rewrote the clone method.

Add feat of force use/nouse cbo rule hint and fix pr
introduce
when not using this hint, cbo rules like INFER_SET_OPERATOR_DISTINCT
would generate two plans and compare their cost
and nereids optimizer would decide which is better. But when we want to
control the behavior of cbo rules we could use this force cbo rule hint
usage example
explain shape plan
select /*+ USE_CBO_RULE(INFER_SET_OPERATOR_DISTINCT) */
*
from t1
union
select * from t2;
the USE_CBO_RULE(INFER_SET_OPERATOR_DISTINCT) hint would force rule
INFER_SET_OPERATOR_DISTINCT to be used
and generate plan like, which hashAgg below union is generated by this
rule:
-- !with_hint_union_distinct --
----hashAgg[GLOBAL]
--------hashAgg[LOCAL]
----------PhysicalUnion
--------------hashAgg[LOCAL]
----------------PhysicalOlapScan[t1]
--------------hashAgg[LOCAL]
----------------PhysicalOlapScan[t2]
Hint log:
Used: INFER_SET_OPERATOR_DISTINCT
UnUsed:
SyntaxError:
When we want to force disable this rule, we could use
explain shape plan select /*+
NO_USE_CBO_RULE(INFER_SET_OPERATOR_DISTINCT) */ * from t1 union select *
from t2;
which would generate plan with this rule:
-- !with_hint_no_union_distinct --
----hashAgg[GLOBAL]
--------hashAgg[LOCAL]
----------PhysicalUnion
--------------PhysicalOlapScan[t1]
--------------PhysicalOlapScan[t2]

## Proposed changes
The JOB's execution SQL is currently defined by an older CUP file, which
causes some issues with lexical analysis in the new optimizer as it
doesn't pass under the old optimizer. Since the JOB's underlying
execution already uses the new optimizer, we're planning to fully
migrate to ANTLR4 for consistency.
