Problem:
when create table as select from a view with unknown length character type, be would return an error of inserting data failed
Example:
doris/regression-test/suites/ddl_p0/test_ctas.groovy
Reason & Solved:
BE can not derive varchar length automaticly so FE should tell BE to maximize the size of varchar type
1. generalized debug point facilities from docker suites for
fault-injection/stubbing cases
2. add segcompaction fault-injection cases for demonstration
3. add -238 TOO_MANY_SEGMENTS fault-injection case for good
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.
Add tpcds sf100 hive shapes.
Disable query64 temporarily because it is not same with emr cluster after collecting metadata by analyze table xxx.
And the root cause need to analyze, will enable in future PR.
remove case
```sql
select datediff('10000-10-31', '2010-10-15')
```
because Nereids throw exception when cast '10000-10-31' to date,
but legacy planner return null on it
we put bound expr into unbound group by list by mistake.
This will lead to bind twice on some exprssion.
Since binding is not idempotent, below exception will be thrown for sql
```sql
select k5 / k5 as nu, sum(k1) from test group by nu order by nu nulls first
```
```
