Add IPv6 support for network attachements

When NETWORK_ISOLATION_IPV6 (default: false) is true, configure the NAD for IPv6. Likewize NETWORK_ISOLATION_IPV4 (default: true) controls if IPv4 is configured. Enabling both IPv6 and IPv4 should work for dual stack. Signed-off-by: Harald Jensås <[email protected]>
