Pods are considered ready while loading and cannot serve

Related: dragonflydb/dragonfly#5881

Problem:
Currently, using the standard Docker healthcheck for both liveness and readiness probes causes issues during rolling updates when:

• New pods pass health checks while still loading datasets into memory
• Kubernetes kills old pods before new pods are truly ready to serve traffic
• This results in service downtime during deployments (3+ minutes as mentioned in #5881)
