Jackson JSON support for spring-boot-starter-jersey

`spring-boot-starter-jersey` does not support JSON out of the box as does spring web. 

I've created a tiny demo here: https://github.com/tadaskay/spring-jersey-demo
Spring controller will return JSON, while Jersey controller will give `500`:
`o.g.j.m.i.WriterInterceptorExecutor      : MessageBodyWriter not found for media type=application/json, type=class demo.beans.HelloBean, genericType=class demo.beans.HelloBean`

Luckily, all that's needed to support jackson is `jersey-media-json-jackson` [module](https://jersey.java.net/documentation/latest/media.html#json.jackson).
