Description

the user doc draft: https://github.com/apache/flink/pull/20577

The LOOKUP hint allows users to suggest the Flink optimizer to: 
1. use synchronous(sync) or asynchronous(async) lookup function
2. configure the async parameters
3. enable delayed retry strategy for lookup

we can verify each one and also some combinations of above features
