Add shortNames to CRDs(#693)

Add `shortNames` to kube api-resource CRDs. Short-names make it easier when interacting/troubleshooting api-resources with kubectl. 

We have tried to follow the naming convention similar to what K8s uses which should help with avoiding any naming conflicts as well. For example:
* `Deployment` has a shortName of deploy, so added rdeploy for `runnerdeployment`
* `HorizontalPodAutoscaler` has a shortName of hpa, so added hra for `HorizontalRunnerAutoscaler`
*  `ReplicaSets` has a shortName of rs, so added rrs for `runnerreplicaset`
