1. Proposed title of this feature request
   Custom Icon's in Topology View
2. What is the nature and description of the request?
   Today you can only change the icon of a application if you adjust the app.openshift.io/runtime (and pick from a small list of runtimes: https://github.com/openshift/console/blob/master/frontend/public/components/catalog/catalog-item-icon.tsx)

To help developers better visualize there applications we should allow them to set a app.openshift.io/runtime-icon label (as well) allowing them to specify a URI to a svg file that better represents their application.
