## Bug Report
**For English only**, other languages will not accept.
Before report a bug, make sure you have:
- Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues).
- Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview).
Please pay attention on issues you submitted, because we maybe need more details.
If no response anymore and we cannot reproduce it on current information, we will **close it**.
Please answer these questions before submitting your issue. Thanks!
### Which version of ShardingSphere did you use?
we find java version: java8, full_version=1.8.0_282
ShardingSphere-5.1.3-SNAPSHOT
Commit ID: 7c67365b394d2e3ac562329b550c135c31ea764d
Commit Message: Avoid overhead of invoking method in Optional.orElse (#18921)
Branch: 7c67365b394d2e3ac562329b550c135c31ea764d
Build time: 2022-07-08T19:24:17+0800
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-Proxy
### Expected behavior
Create/alter traffic related distsql syntax are supported
### Actual behavior
Create/alter traffic related distsql syntax are not supported
### Reason analyze (If you can)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
CREATE TRAFFIC RULE sql_hint_traffic_2(LABELS(OLAP, order_by),TRAFFIC_ALGORITHM(TYPE(NAME= SQL_HINT)));
```
order_db=> CREATE TRAFFIC RULE sql_hint_traffic_2(LABELS(OLAP, order_by),TRAFFIC_ALGORITHM(TYPE(NAME= SQL_HINT)));
ERROR: Traffic load balance algorithm can not be null.
order_db=>
order_db=> show traffic rules from traffic_db;
ERROR: Rule `TrafficRule` should have and only have one instance.
order_db=> CREATE TRAFFIC RULE sql_hint_traffic_2(LABELS(OLAP, order_by),TRAFFIC_ALGORITHM(TYPE(NAME= SQL_HINT)),LOAD_BALANCER(TYPE(NAME=ROUND_ROBIN)));
ERROR: Rule `TrafficRule` should have and only have one instance.
```
### Example codes for reproduce this issue (such as a github link).
