Ensure readiness probe is configured for containers in all Kubernetes workloads

Having a readiness probe configured will help ensure that a container is functional throughout the container lifecycle. If the workload is not showing as ready in accordance with the probe, traffic will not be sent to it. This helps reduce errors and can provide stability. For more information on readiness probes, see the Kubernetes documentation.
