API: Difficulty attribute update part 2

[PlesnikJakub]

Description

In #75 we implemented a range validator for the difficulty attribute of the Question object. The existing solution is great for validation on API but we should also extend our domain of such rules so the domain is holding the business rules.

in CreateQuestionInput.cs and UpdateInterviewQuestionInput.cs:

• change the Difficulty attribute to not nullable
• add validation check to the init method that the value is between 0 - 100
• throw an exception ArgumentOutOfRangeException if difficulty is not valid
• cover it with tests

Furthermore, a similar rule can be added to the infrastructure layer of the EF entity.

[Range(0,100)]
public int Difficulty { get; set; }

Acceptance Criteria

• [ ] Application layer contains rules for difficulty attribute
• [ ] 100% coverage on a new code
• [ ] All tests are passing
