Deployments

Somewhat more difficult than, namespaces, as arbitrary JSON doesn't seem to play nicely with the K8s code generators.

The main changes from the Ververica Platform are:

• resource CPU must be a Quantity string, though this should normally just mean you must quote your value
• You can specify a spec.deploymentTargetName instead of an ID

You can find an example in config/samples/ververicaplatform_v1beta1_vpdeployment.yaml.
