Vapor: 4.10.3 Release

This patch was authored by @seeppp and released by @MrLotU.

Validations now follows required argument while validating nested validations.

If we add a validation step of a nested object, which is optional, the required flag would be set false.

validations.add("optionalNestedObject", required: false, B.validations)

Therefore, we are now able to have an object like this: ```swift struct A: Codable { var name: String var optionalNestedObject: A? }

extension A: Validatable { static func validations(_ validations: inout Validations) { validations.add("name", as: String.self, is: .ascii) validations.add("optionalNestedObject", required: false, A.validations) } } `` The validator now validates the nested object only ifoptionalNestedObject != nil`.

If the nested object is non-optional, you can still omit the required argument. swift validations.add("nestedObject", B.validations)
