This adds support for IPV6 network LBs.
These can only be used if all cluster nodes are fully dual stack enabled.

This also changes the behavior for other LBs slightly.
We will now only add ready nodes to the LB config.
The defaults in certain cases change depending on what the nodes in the
cluster support. If there's a mix of old and new nodes, we keep the old
behavior until the last old node is gone.

The LB health checks will take care of this.
