[chart/redis-ha] allow creation of network policies for haproxy

[dani-CO-CN]

Is your feature request related to a problem? Please describe. i use this helm chart as a dependency in the argocd helm chart, currently i could not find away to create network policies for haproxy.

Describe the solution you'd like add a network policy template for haproxy pods to the helm chart, this would allow me to just inject my ingress/egress blocks as values.

haproxy:
  netpol:
    enabled: true
    ingress:
    - from:
      - podSelector:
          matchLabels:
            app: argocd
      ports:
      - port: the_redis_port
        protocol: TCP
