* [Java] [JavaJaxRS] Respect readOnly/writeOnly attribute markers
Generate jackson JsonProperty like following:
- `readOnly` is present in Spec: `@JsonProperty(value = "[name]", access = JsonProperty.Access.READ_ONLY)`
- `writeOnly` is present in Spec: `@JsonProperty(value = "[name]", access = JsonProperty.Access.WRITE_ONLY)`
Edge case: both are present -> Spec is invalid and generator cancels anyway with:
> org.openapitools.codegen.SpecValidationException: There were issues with the specification. The option can be disabled via validateSpec (Maven/Gradle) or --skip-validate-spec (CLI).
> | Error count: 1, Warning count: 1
> Errors:
> -attribute components.schemas.Example. writeOnly and readOnly are both present
* update samples
