feat(kube-vip): add support for volumes and hostaliases configuration

[acamilleri]

Add support to set additional volumes, volumeMounts and hostAliases.

I'm using KubeVIP with K3S and I need to pass the kubeconfig into the container and define 127.0.0.1 as kubernetes host aliases.

volumes:
  - hostPath:
     path: /etc/rancher/k3s/k3s.yaml
     type: File
     name: kubeconfig
     
volumeMounts:
  - mountPath: /etc/kubernetes/admin.conf
    name: kubeconfig

hostAliases:
  - hostnames:
      - kubernetes
    ip: 127.0.0.1

#54 seems to be working as intended so if this gets merged we should finally have an updated chart published in the helm repo. Currently the latest available is still 0.6.1.

Yes, but release 0.6.3 already exist. What I'm supposed to do ? I switch the chartVersion to 0.6.2 ?

No, the version in this MR is right. I'm saying it will be a good thing to have it merged and published because it will trigger an update. :)
