 Review comment:
   @maropu The strategy field `fixedPoint` of Analyzer/Optimizer is determined 
when analyzer/optimizer initialized, thus SQLConf will not affect their 
behavior during runtime. `getAnalyzer()` only support makeAnalyzer with 
CASE_SENSITIVE config, while I think adding more config such as 
ANALYZER_MAX_ITERATIONS to `getAnalyzer()` will be too specific. That’s why I 
introduced this helper method with SQLConf input parameter, which will also 
support future test case requirements like ANALYZER_MAX_ITERATIONS does. Thanks!
