gd2-4295 minor refactor, optimization - #9

Nullability of reference types in type of parameter 'properties' of 'Task AuthenticationRequestHandlerWrapper.ForbidAsync(AuthenticationProperties properties)' doesn't match implicitly implemented member 'Task IAuthenticationHandler.ForbidAsync(AuthenticationProperties? properties)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'properties' of 'Task AuthenticationRequestHandlerWrapper.ChallengeAsync(AuthenticationProperties properties)' doesn't match implicitly implemented member 'Task IAuthenticationHandler.ChallengeAsync(AuthenticationProperties? properties)' (possibly because of nullability attributes).

Cannot convert null literal to non-nullable reference type.

Cannot convert null literal to non-nullable reference type.

Nullability of reference types in type of parameter 'name' of 'ValidateOptionsResult KeyRotationOptionsValidator.Validate(string name, KeyRotationOptions options)' doesn't match implicitly implemented member 'ValidateOptionsResult IValidateOptions<KeyRotationOptions>.Validate(string? name, KeyRotationOptions options)' (possibly because of nullability attributes).

'ISystemClock' is obsolete: 'Use TimeProvider instead.'

Nullability of reference types in return type of 'Task<CorsPolicy> CorsPolicyProvider.GetPolicyAsync(HttpContext context, string policyName)' doesn't match implicitly implemented member 'Task<CorsPolicy?> ICorsPolicyProvider.GetPolicyAsync(HttpContext context, string? policyName)'.
