Hazelcast Kubernetes configuration

[gbbirkisson]

I want to be able to configure HZ K8s plugin further. Now XP does not provide this option.

See this for reference: https://github.com/hazelcast/hazelcast-kubernetes/tree/v1.5.5

What I need to be able to set:

hazelcast:
  network:
    join:
      kubernetes:
        enabled: true
        namespace: MY-KUBERNETES-NAMESPACE
        service-name: MY-SERVICE-NAME
        resolve-not-ready-addresses: true

Nice to have:

hazelcast:
  network:
    join:
      kubernetes:
        service-label-name: ?
        service-label-value: ?
        pod-label-name: ?
        pod-label-value: ?
        use-node-name-as-external-address: true
        kubernetes-api-retries: 5

partition-group:
  enabled: true
  group-type: NODE_AWARE

Hardly useful, pretty much never set manually:

hazelcast:
  network:
    join:
      kubernetes:
        kubernetes-master: ?
        api-token: ?
        ca-certificate: ?
        service-port: ?

All from "Need" and "Nice to have" could be done. We won't implement "Hardly useful"

group-type: NODE_AWARE is little bit tricky. It is a general setting, not related to K8S directly, but sure, let's try it out.
