Support enableServiceLinks in Pod Specs.

[HamishWHC]

Description of the feature or enhancement:

Pods and workloads that define pods (e.g. Deployments, StatefulSets, etc) should have the enableServiceLinks property that defines whether the pod has service discovery environment variables defined.

Use Case:

I need to be able to disable this option across many workloads, and would prefer to have a better way than applying JSON patches.

Proposed Solution:

Addition of enableServiceLinks: boolean to AbstractPodProps. I haven't played with the CDK8s-plus internels yet so there may also be runtime manipulation needed.
