Upgrade to Jackson 2.10.0

[linux-china]

Now scalecube-cluster use jackson 2.10.0.pr1

<jackson.version>2.10.0.pr1</jackson.version>

But some api removed in Jackson 2.10.0 and DefaultObjectMapper.java can not work because of following code:

 mapper.enableDefaultTyping(
        LaissezFaireSubTypeValidator.instance,
        DefaultTyping.JAVA_LANG_OBJECT,
        JsonTypeInfo.As.WRAPPER_OBJECT);

enableDefaultTyping has been removed from Jackson 2.10.0

Could we change DefaultObjectMapper to public? For some cases, if you use Jackson for en/decoding, maybe want to call Objecct.registerModule() to register some module, and now it's hard because DefaultObjectMapper is not public.

I did some testing, and now DefaultObjectMapper is not compatible with CloudEvents Java SDK, and can not en/decoding CloudEventImpl https://github.com/cloudevents/sdk-java/blob/master/api/src/main/java/io/cloudevents/v1/CloudEventImpl.java

        DefaultObjectMapper.OBJECT_MAPPER.registerModule(new Jdk8Module());
        final SimpleModule module = new SimpleModule();
        module.addSerializer(ZonedDateTime.class, new ZonedDateTimeSerializer());
        module.addDeserializer(ZonedDateTime.class, new ZonedDateTimeDeserializer());
        DefaultObjectMapper.OBJECT_MAPPER.registerModule(module);

Regarding Jdk8Module. Create a PR with changes in corresponding pom\s (it's just another jackson dependency) and we will have Jdk8Module. Regarding DefaultObjectMapper -- his purpose is not modifications but as the name says it's default. If u need custom object mapper use corresp. constructor on corresp. codec class.

@artem-v yes, you are right. Just upgrade to Jackson 2.10.0 and add Jdk8Module support. For customized ObjectMapper, and you can create your JacksonMessageCodec and make it loaded by ServiceLoader.
