Support EKS/K8S Only IPv6

[nuvme-devops]

Hello,

I'm getting some errors when deploying K8Ssandra via HELM on an IPv6 only EKS.

I noticed in the logs that cassadra uses 0.0.0.0, but I didn't find it in the ConfigMap where I can change it.

I found something related to these parameters:

JAVA_OPTS="value: -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv4Addresses=true"
listen_interface_prefer_ipv6

Is there support for K8S IPv6?

K8ssandra hasn't been tested on IPv6.
It's a certainty that k8ssandra v1 will not be patched for IPv6 support, but that ticket can be moved to the k8ssandra-operator project if it doesn't work either with IPv6.
