Add a specific label to the integration pod

[abouchama]

It can be useful to pass a label in kamel command that will be set in the integration pod.

This can help for example to group pods under the same service in OpenShift.

At least an "app" label should be added to the integration pod, otherwise it will not be visible at all in the topology view.

This can be now done with:

kamel run Routes.java --label app=pippo -t owner.target-labels=app

The new topology view displays integrations even without app.
