[improvement](tablet-repair) add a config repair_slow_replica (#7423)

Add a new FE config `repair_slow_replica`    
when this config is true, Doris will try to delete the replica
with the largest number of versions, and then rebalance the replica.
Usually, when the number of versions of a certain replica is much higher
then that of other replicas, there are some problems with the current be's compilation.
Migrating to other machines can typically solve this problem.

Apache Doris (incubating)

License Total Lines GitHub release Join the chat at https://gitter.im/apache-doris/Lobby

Doris is an MPP-based interactive SQL data warehousing for reporting and analysis. Its original name was Palo, developed in Baidu. After donated to Apache Software Foundation, it was renamed Doris.

  • Doris provides high concurrent low latency point query performance, as well as high throughput queries of ad-hoc analysis.

  • Doris provides batch data loading and real-time mini-batch data loading.

  • Doris provides high availability, reliability, fault tolerance, and scalability.

The main advantages of Doris are the simplicity (of developing, deploying and using) and meeting many data serving requirements in a single system. For details, refer to Overview.
