Enhancement Description

• One-line enhancement description (can be used as a release note):

Optional Service Environment Variables

• Kubernetes Enhancement Proposal:

This enhancement allows application developers to choose whether their Pods will receive environment variables from services in their namespace. They can choose to disable them via the new enableServiceLinks field in PodSpec. The current behaviour will continue to be the default behaviour, but the developer may choose to disable these environment variables for certain workloads for reasons such as incompatibilities with other expected environment variables or scalability issues.
