disable public ipv4 / ipv6 ignored on autoscaled nodes

[benkrej]

Hi, the enable_public_net_ipv4 parameter seems to be ignored on autoscaled nodes.
I have used the example config and set enable_public_net_ipv4 & enable_public_net_ipv6 to false as well as configured a private network for the static nodes which works flawlessly.
Autoscaled nodes are also set up correctly to use the private network but they are assigned a public ipv4 & ipv6 address.

Awesome tool btw :)
