Main changes:
1. If fqdn is enabled in the configuration file, when fe starts, localAddr will obtain fqdn instead of IP, priority_ Networks will fail
2. The IP and host names of Backend and Front are combined into one field, host. When fqdn is enabled, it represents the host name, and when not enabled, it represents the IP address
3. The communication between clusters directly uses fqdn, and various Connection pool add authentication mechanisms to prevent the IP address of the domain name from changing and the connection between nodes from making errors
4. No longer requires polling to verify if the IP has changed, delete fqdnManager
5. Change the method of verifying the legitimacy of nodes between FEs from obtaining client IP to displaying the identity of the transmitting node itself in the HTTP request header or the message body of the throttle
6. When processing the heartbeat, if BE finds that the host stored by itself is inconsistent with the host stored by the master, after verifying the legitimacy of the host, it will change its own host instead of directly reporting an error
7. Simplify the generation logic of fe name
Scope of influence:
1. Establishing communication connections between clusters
2. Determine whether it is the same node through attributes such as IP
3. Print Log
4. Information display
5. Address Splicing
6. k8s deployment
7. Upgrade compatibility
Test plan:
1. Change the IP address of the node, while keeping the fqdn unchanged, change the IP addresses of fe and be, and verify whether the cluster can read and write data normally
2. Use the master code to generate metadata, and use the previous metadata on the current pr to verify whether it is compatible with the old version (upgrading is no longer supported if fqdn has been enabled before)
3. Deploy fe and be clusters using k8s to verify whether the cluster can read and write data normally
4. According to https://doris.apache.org/zh-CN/docs/dev/admin-manual/cluster-management/fqdn?_highlight=fqdn#%E6%97%A7%E9%9B%86%E7%BE%A4%E5%90%AF%E7%94%A8fqdn Upgrading old clusters
5. Use streamload to specify the fqdn of fe and be to import data separately
6. Use different users to start transactions and write data using insert statements
1. fixed some error regressions (results error with big nstance_num due to incorrect order by).
2. if set parallel_fragment_exec_instance_num to 0, the concurrency in the Pipeline execution engine will automatically be set to half of the number of CPU cores.
3. add limit to parallel_fragment_exec_instance_num that it cannot be set to more than fe.conf::max_instance_num(Default: 128)
```
mysql [(none)]>set parallel_fragment_exec_instance_num = 514;
ERROR 1231 (42000): errCode = 2, detailMessage = Variable 'parallel_fragment_exec_instance_num' can't be set to the value of '514(Should not be set to more than 128)'
```
change tpcds q67 testcase name to q67_ignore_temporarily since the error should be ignored temporarily
due to precision problem that will be fixed further.
Supplement the documentation of be-clion-dev, avoid the problem of undefined DORIS_JAVA_HOME and inability to find jni.h when using clion development without directly compiling through build.sh
Complete the classification of header files in pch.h and introduce some header files that are not frequently modified in doris.
Separate the declaration and definition in common/config.h. If you need to modify the default configuration now, please modify it in common/config.cpp.
gen_cpp/version.h is regenerated every time it is recompiled, which may cause PCH to fail, so now you need to get the version information indirectly rather than directly.
Only 2000 union will cause BE use a lot of memory, so that I enable other test in this PR only disable 2000 union case.

Add table level statistics, support SHOW TABLE STATS statement to show table level statistics.
Implement automatically analyze statistics, support ANALYZE... WITH AUTO ... statement to automatically analyze statistics.
TODO:
collate relevant p0 tests
Supplement the design description to README.md
Issue Number: close #xxx
- Implements ORC lazy materialization, integrate with the implementation of https://github.com/apache/doris-thirdparty/pull/56 and https://github.com/apache/doris-thirdparty/pull/62.
- Refactor code: Move `execute_conjuncts()` and `execute_conjuncts_and_filter_block()` in `parquet_group_reader `to `VExprContext`, used by parquet reader and orc reader.
- Add session variables `enable_parquet_lazy_materialization` and `enable_orc_lazy_materialization` to control whether enable lazy materialization.
- Modify `build.sh` to update apache-orc submodule or download package every time.
when I use mysql-jdbc 5.1.47 create a doris jdbc catalog, the largeint cannot select
When mysql-jdbc reads largeint, it will convert the format to string because it is too long
mysql> select `largeint` from type3;
ERROR 1105 (HY000): errCode = 2, detailMessage = (127.0.0.1)[INTERNAL_ERROR]Fail to convert jdbc type of java.lang.String to doris type LARGEINT on column: largeint. You need to check this column type between external table and doris table.
Support querying data from the Nebula graph database
This feature comes from the needs of commercial customers who have used Doris and Nebula, hoping to connect these two databases
changes mainly include:
* add New Graph Database JDBC Type
* Adapt the type and map the graph to the Doris type
Fix errors when read boolean type from external doris cluster by jdbc catalog:
```
ERROR 1105 (HY000): errCode = 2, detailMessage = (172.16.10.11)[INTERNAL_ERROR]Fail to convert jdbc type of java.lang.Integer to doris type BOOL on column: deleted.
You need to check this column type between external table and doris table.
```
MySQL Types and Return Values for GetColumnTypeName and GetColumnClassName are presented in https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-reference-type-conversions.html.
However when tinyInt1isBit=false, GetColumnClassName of MySQL returns java.lang.Boolean, while that of Doris returns java.lang.Integer. In order to be compatible with both MySQL and Doris, Jdbc params should set tinyInt1isBit=true&transformedBitIsBoolean=true
