Add missing probes for Redis Kubernetes manifest

Problem to solve

Redis Deployment manifests for Kubernetes doesn't provides "health probes" examples.

Proposal

Add health probes examples

livenessProbe:
  exec:
    command:
    - redis-cli
    - ping
  failureThreshold: 3
  periodSeconds: 5
  successThreshold: 1
  timeoutSeconds: 1

readinessProbe:
  failureThreshold: 3
  periodSeconds: 5
  successThreshold: 1
  tcpSocket:
    port: redis
  timeoutSeconds: 1

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
