[feature-wip](statistics) support statistics injection and show statistics
(#14201)
1. Reduce the configuration options for statistics framework, and add
comment for those rest.
2. Move the logic of creation of analysis job to the `StatisticsRepository`
which defined all the functions used to interact with internal statistics table
3. Move AnalysisJobScheduler to the statistics package
4. Support display and injections manually for statistics
