JIRA: https://jira.spring.io/browse/INT-4267Fixes: spring-projects/spring-integration#2110
The documentation clearly point that we can simply use JSON (de)serialization
with the `RedisMessageStore`, but actually it isn't so easy
* Fix `MessageGroupMetadata`, `MessageHolder`, `MessageMetadata` for Jackson
deserialization compatibility
* Add `MessageHeaders`-based ctor to the `AdviceMessage`
* Add `MessageHeadersJacksonSerializer` to serialize `MessageHeaders`
to the `HashMap` for easier deserialization afterwards
* Add deserializer implementations for all `Message` types
* Add convenient `JsonObjectMapperProvider#jacksonMessageAwareMapper()`
factory method to build `ObjectMapper` supplied with mentioned above
(de)serializers
**Cherry-pick to 4.3.10 without `MessageHolder` and `MessageMetadata`**
