Is your feature request related to a problem? Please describe.
We currently only know the API to where we deployed a model, but not what image and so forth

Describe the solution you'd like
Add a new entity called KubernetesDeploymentInfo. It should hold the following values

• RegistryName
• ImageName
• NamespaceName
• ServiceName
