camel-rest should load automatically for routes using Rest DSL

[tadayosi]

Currently examples/RestWithRestlet.java fails unless --dependency=camel-rest is explicitly set:

$ kamel run --name=rest-with-restlet --dependency=camel-restlet examples/RestWithRestlet.java --dev

Which version of camel-k you are using? I could not reproduce this issue using version 0.3.4

Below is a log of the steps taken to reproduce.

On another tab creating a proxy to integration.

$ kubectl port-forward rest-with-restlet-694996b794-x7jc7 8080:8080
Forwarding from [::1]:8080 -> 8080
Forwarding from 127.0.0.1:8080 -> 8080

Finally on a third tab testing the service

$ curl localhost:8080/hello
Hello World

@ipolyzos Yeah, I should've noted that it was an issue with the latest snapshot, which uses Camel 3.0.0-M4 so camel-rest is no longer automatically available:

$ kamel version 
Camel K Client 1.0.0-M1-SNAPSHOT

[pabloxtiyo]

Im having the same behavior :/
