Kamel uninstall leftovers

[ipolyzos]

On a clean namespace i.e

  $ kubectl get all,pvc,configmap,rolebindings,clusterrolebindings,secrets,sa,roles,clusterroles,crd -l 'app=camel-k'
  No resources found in default namespace.

When I try to uninstall a new clean installation of Camel-k not all resources removed. The crd and clusterrole remain installed i.e

  $ kamel install 
  Camel K installed in namespace default 
  $ kamel uninstal
  Camel K Integration Platform removed from namespace default
  Camel K Config Maps removed from namespace default
  Camel K Operator removed from namespace default
  Camel K Role Bindings removed from namespace default
  Camel K Roles removed from namespace default
  Camel K Service Accounts removed from namespace default
  $ kubectl get all,pvc,configmap,rolebindings,clusterrolebindings,secrets,sa,roles,clusterroles,crd -l 'app=camel-k'

Fix submitted. I can confirm now that on a clean namespace i.e

$ kubectl get all,pvc,configmap,rolebindings,clusterrolebindings,secrets,sa,roles,clusterroles,crd -l 'app=camel-k'                                                                     git:(master|✚2 
No resources found in default namespace.

When I try to uninstall a clean installation of Camel-k the CRD and ClusterRole are also removed i.e

$ kamel install 
Camel K installed in namespace default

See comment on #1466 (comment)

Maybe we can document that for a complete uninstall you should pass some additional flags, but I wouldn't do it by default.

@nicolaferraro a provisional change in the docs issued with PR #1475, if you could please review it would be great
