{code}

The spring-boot POM and dependencies are a bit messed up, so I had to add a bunch of dependencies
manually, and had to add spring 5, and reactor and some other stuff, and also undertow did
not work so used tomcat, and some problems with webmvc etc.

>
> We should try get started with the migration effort for getting Camel running on Spring
Boot 2.0.x.
> There may be issues with the starter component as Spring Boot guys changed stuff how
auto configuration and setting properties works. So we may need to have some kind of interface
in camel-spring-boot and camel-spring-boot2 where we can have different implementation that
the -starter can use.
