> When subtract resources finished, we need to call {{Resources::validate}} to check if the scalar resource is negative so as to remove this resource if it is negative. This is a bit heavy as the {{Resources::validate}} did many validation stuffs, such as checking type, validating role, checking resource name etc, all of them are not necessary.
> We should introduce a new helper function {{isNegative}} to check if the resource is a negative scalar resource.
