fix bugs of lateral view with CTE or where clause.
The error case can be found in newly added tests in `TableFunctionPlanTest.java`
But there are still some bugs not being fixed, so the unit test is annotated with @Ignore
This PR contains the change is #7824 :
> Issue Number: close#7823
>
> After the subquery is rewritten, the rewritten stmt needs to be reset
> (that is, the content of the first analyze semantic analysis is cleared),
> and then the rewritten stmt can be reAnalyzed.
>
> The lateral view ref in the previous implementation forgot to implement the reset function.
> This caused him to keep the first error message in the second analyze.
> Eventually, two duplicate tupleIds appear in the new stmt and are marked with different tuple.
> From the explain string, the following syntax will have an additional wrong join predicate.
> ```
> Query: explain select k1 from test_explode lateral view explode_split(k2, ",") tmp as e1 where k1 in (select k3 from tbl1);
> Error equal join conjunct: `k3` = `k3`
> ```

> This pr mainly adds the reset function of the lateral view
> to avoid possible errors in the second analyze
> when the lateral view and subquery rewrite occur at the same time.
Let the build process stop immediately if some command execute failed.
For example, patch failed due to command not found, otherwise it will stop until compile error.

Support create Iceberg external table in Doris.
This is the first step to support Iceberg external table.
### Create Iceberg external table
This pr describes two ways to create Iceberg external tables. Both ways do not require explicitly specifying column definitions, Doris automatically converts them based on Iceberg's column definitions.
1. Create an Iceberg external table directly
```sql
CREATE [EXTERNAL] TABLE table_name
ENGINE = ICEBERG
[COMMENT "comment"]
PROPERTIES (
"iceberg.database" = "iceberg_db_name",
"iceberg.table" = "icberg_table_name",
"iceberg.hive.metastore.uris" = "thrift://192.168.0.1:9083",
"iceberg.catalog.type" = "HIVE_CATALOG"
);
```
2. Create an Iceberg database and automatically create all the tables under that db.
```sql
CREATE DATABASE db_name
[COMMENT "comment"]
PROPERTIES (
"iceberg.database" = "iceberg_db_name",
"iceberg.hive.metastore.uris" = "thrift://192.168.0.1:9083",
"iceberg.catalog.type" = "HIVE_CATALOG"
);
```
### Show table creation
1. For individual tables you can view them with `help show create table`.
```sql
mysql> show create table iceberg_db.logs_1;
+--------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| Table | Create Table |
+--------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
| logs_1 | CREATE TABLE `logs_1` (
`level` varchar(-1) NOT NULL COMMENT "null",
`event_time` datetime NOT NULL COMMENT "null",
`message` varchar(-1) NOT NULL COMMENT "null"
) ENGINE=ICEBERG
COMMENT "ICEBERG"
PROPERTIES (
"iceberg.database" = "doris",
"iceberg.table" = "logs_1",
"iceberg.hive.metastore.uris" = "thrift://10.10.10.10:9087",
"iceberg.catalog.type" = "HIVE_CATALOG"
) |
+--------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
```
2. For Iceberg database, you can view it with `help show table creation`.
```sql
mysql> show table creation from iceberg_db;
+--------+---------+---------------------+---------------------------------------------------------+
| Table | Status | Create Time | Error Msg |
+--------+---------+---------------------+---------------------------------------------------------+
| logs | fail | 2021-12-14 13:50:10 | Cannot convert unknown type to Doris type: list<string> |
| logs_1 | success | 2021-12-14 13:50:10 | |
+--------+---------+---------------------+---------------------------------------------------------+
2 rows in set (0.00 sec)
```
This is a new syntax.
Show table creation records in Iceberg database:
Syntax:
```sql
SHOW TABLE CREATION [FROM db] [LIKE mask]
```
`insert` statement may return exception message `Execute timeout` after load data failed.
But the real reason is that there exists unhealthy backend, not execute timeout.
```
MySQL [ssb]> insert into lineorder_flat select * from lineorder_flat;
ERROR 1105 (HY000): errCode = 2, detailMessage = Execute timeout
```
When using linked schema change, we need to check if all rowsets are of the same type,
ALPHA or BETA. otherwise, we need to use direct schema change to convert the data.
Currently, if we encounter a problem with a replica of a tablet during the load process,
such as a write error, rpc error, -235, etc., it will cause the entire load job to fail,
which results in a significant reduction in Doris' fault tolerance.
This PR mainly changes:
1. refined the judgment of failed replicas in the load process, so that the failure of a few replicas will not affect the normal completion of the load job.
2. fix a bug introduced from #7754 that may cause BE coredump
Fix the following bugs.
1. `column1` created a bitmap index.
2. `column1` has a lot index items in the bitmap index, and the index page is divided into two levels.
3. `column1`'s value range is `[1000, 10000000]`.
4. the query condition is `column1 > 0`
5. the empty result will be returned, while the expected value should be 9999000 rows.
This PR mainly changes:
1. Help to Cancel the load job ASAP when encounter unqualified data.
Solution is described in #6318 .
Also replace some std::stringstream with fmt::memory_buffer to avoid performance issues.
2. fix a NPE bug when create user with empty host
3. fix compile warning after rebasing the master(vectorization)
1. Add a new FE config `colocate_group_relocate_delay_second`
The relocation of a colocation group may involve a large number of tablets moving within the cluster.
Therefore, we should use a more conservative strategy to avoid relocation of colocation groups as much as possible.
Relocation usually occurs after a BE node goes offline or goes down.
This config is used to delay the determination of BE node unavailability.
The default is 30 minutes, i.e., if a BE node recovers within 30 minutes, relocation of the colocation group
will not be triggered.
2. Change the priority of colocate tablet repair and balance task from HIGH to NORMAL
3. Add a new FE config allow_replica_on_same_host
If set to true, when creating table, Doris will allow to locate replicas of a tablet
on same host. And also the tablet repair and balance will be disabled.
This is only for local test, so that we can deploy multi BE on same host and create table
with multi replicas.

## Problem Summary:
### 1. Some code from clickhouse
**ClickHouse is an excellent implementation of the vectorized execution engine database,
so here we have referenced and learned a lot from its excellent implementation in terms of
data structure and function implementation.
We are based on ClickHouse v19.16.2.2 and would like to thank the ClickHouse community and developers.**
The following comment has been added to the code from Clickhouse, eg:
// This file is copied from
// https://github.com/ClickHouse/ClickHouse/blob/master/src/Interpreters/AggregationCommon.h
// and modified by Doris
### 2. Support exec node and query:
* vaggregation_node
* vanalytic_eval_node
* vassert_num_rows_node
* vblocking_join_node
* vcross_join_node
* vempty_set_node
* ves_http_scan_node
* vexcept_node
* vexchange_node
* vintersect_node
* vmysql_scan_node
* vodbc_scan_node
* volap_scan_node
* vrepeat_node
* vschema_scan_node
* vselect_node
* vset_operation_node
* vsort_node
* vunion_node
* vhash_join_node
You can run exec engine of SSB/TPCH and 70% TPCDS stand query test set.
### 3. Data Model
Vec Exec Engine Support **Dup/Agg/Unq** table, Support Block Reader Vectorized.
Segment Vec is working in process.
### 4. How to use
1. Set the environment variable `set enable_vectorized_engine = true; `(required)
2. Set the environment variable `set batch_size = 4096; ` (recommended)
### 5. Some diff from origin exec engine
https://github.com/doris-vectorized/doris-vectorized/issues/294
