[Java][Jersey] Add support for BeanValidation @Valid annotation

Created by: fujigon

Description

Java Jersey generator has same issue with https://github.com/swagger-api/swagger-codegen/issues/4738 (fixed by https://github.com/swagger-api/swagger-codegen/pull/7807 for jaxrs-cxf)

Without @Valid, constraint annotations will not be evaluated. So we need to add not only constraint annotations such as @NotNull, but also @Valid.

openapi-generator version

current master (2d99836e)
