It is possible to customize the Application Menu entry of Hawtio Online in the Openshift Console by sepcifying thw following in the CR:

apiVersion: hawt.io/v1
kind: Hawtio
spec:
  config:
    online:
      consoleLink:
        text: Hawtio Online
        imageRelativePath: /icons/poweredby.png

The imageRelativePath property must be relative to the route host hence is currently limited as to what icons can be used (the poweredby icon is a Red Hat branded image).

Need a way to inject such icons into the path, maybe via including them in a configmap (another one??) or including them directly in the CR using base64 (CSVs do it).
