control-service: add config.contacts.present to the graphQL schema

[mrMoZ1]

What is the feature request? What problem does it solve? Users can sort by this field introduced in this change https://github.com/vmware/versatile-data-kit/pull/582, however the field is not present in the graphQL schema. We should add it to the schema.

Suggested solution V2DataJobContact class to return in the graphQL API which will have the extra property and translate the openApi generated in a similar fashion to other V2 classes in the graphQL model. Refactor all APIs that use it and make sure we don't introduce regressions.
