#1037 Improve architecture of registration methods (#236)

* #1037 Improve architecture of registration methods
- Introduce parameters classes for each registration method
- RegistrationMethod has constants with the required parameters class -> no longer need to have a RegistrationExecutorProvider class that needs to be injected everywhere, let AsyncRegister be the only one to worry about which class will perform the registration
- Fix inheritance of password registration types - previously two-factor auth registration inherited from password registration directly

* Create matcher which checks for equality via reflections
- Allow to perform equality check on objects with default equals() method
