Moved members stats code out of members controller

Browse Source 
refs #12537

- `stats` method in members controller is quite big and does much more then controller method code should - few calls to relevant modules
- Extracted code "as is" into members serivce
- Next step will be to refactor this module as a class pattern with DI parameters
