Result type inconsistency with AuthorizationResult and ValidationPassedResult #9
Description
There is some Result type confusion/inconsistency with AuthorizationResult and ValidationPassedResult.
AuthorizationResult is in the Results namespace, but is not an actual Result subclass. It was originally intended to be used with an IAuthorizer<T> interface that was not yet ported to this library. This should be moved out and renamed (TBD).
ValidationPassedResult is only intended to be used with IValidator<T>, not as an actual result type from a command or query handler, which is technically possible today since it ultimately subclasses Result through ValidationResult. We should separate out validation outputs from the Result hierarchy.
