[Enhancement] Allow user to set value enumeration for a sonata property in Request mapping and add Validation

[miyaflowercat]

As a control plane user, when I create request mapping between sonata API and target API, I could be able to add value enumeration for specific sonata properties

e.g. bandwidth range [1000, 10000]

later when this sonata use case is triggered, kraken will do request property value validation for those properties that user set value enumerations

• if pass validation, kraken will continue the processing
• if failed, kraken will fail the request with 422
