Add KubernetesDeploymentInfo as an associated entity to Deployment

**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

Start by locating the Deployment entity and existing associated-entity patterns in MLOps.NET, then inspect how Kubernetes deployment metadata is currently represented. Done means Deployment exposes a KubernetesDeploymentInfo entity containing RegistryName, ImageName, NamespaceName, and ServiceName, with the relevant tests passing.
