WithFailFastStrategy - fail fast, but only in the related scope

[bartoszlenar]

Feature description

• Ability to set the fail-fast strategy in a single scope.

Feature in action

Specification<Model> specification = s => s
    .Member(m => m.Member, memberSpecification).WithFailFastStrategy();

Specification<Model> specification = s => s
    .AsModel(anotherSpecification).WithFailFastStrategy();

Feature details

• New parameter command: WithFailFastStrategy.
• The related scope command would terminate and return error output immediately after detecting a single error.
• Internally it looks like temporary setting FailFast to true in the ValidationContext class, but let's investigate that further.
