Kikyou1997 e82d8433be [feature](nereids) Integrate nereids into current SQL process framework (#10304 )

To integrate the nereids optimizer with new SQLParser and Planner to existing SQL process framework, I abstract a interface which named "Planner" and let the Both planner from nereids and stale optimizer implement it, to disguish it
with origin Planner, I rename the Planner to OriginalPlanner.

As we don't want to impact the existing logic too much, I defined a LogicalPlanAdapter to adapt the logicalPlan that is the output of the new paser to the existing code.

Besides, as the MySQL protocol supports sending multiple statements in one packet, so I add Nereids#SparseSQL method to handle this properly.

Apache Doris

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.

Technology
