Explorer, Properties: Allow a user to scale their deployment

The web and cli allows a user to scale their deployments, which is only possible now in Eclipse by editing the replicationcontroller. Add UI to facilitate scaling. Scaling should be allowed in some sort of context menu when selecting any of:

1. deployment (replication controller)
2. eclipse view of a deployment (service) -> walk back to the currrent deployment
3. pod -> walk back to the current deployment

updating 'spec.replicas' causes a new pods to spin up
