fix a couple of compiler warnings

- [WARNING] Annotation: javax.validation.constraints.NotNull on property: getName is deprecated. Please use: io.fabric8.generator.annotation.Required instead
- [WARNING] kaap/operator/src/main/java/com/datastax/oss/kaap/crds/GlobalSpec.java:[42,1] Generating equals/hashCode implementation but without a call to
  superclass, even though this class does not extend java.lang.Object. If this is intentional, add '@EqualsAndHashCode(callSuper=false)' to your type.
