See KOGITO-4741 for context.

Users might have specifics requirements for how the application container/pod spec needs to be created in their cluster. KOGITO-4741 is one of them. Another good reference for this scenario is https://github.com/m88i/nexus-operator/issues/28.

Instead of cherry-picking these attributes and adding them to our interface, it would be better to expose the entire container spec, similarly to what Knative Serving already does: https://knative.dev/docs/serving/getting-started-knative-app/#creating-your-deployment-with-yaml.
