Set default external port to noop for puppet
Set default external port to noop for puppet

In 9b89dd20162d962480d3cb84161ed6bfd4fa9de8 we had a regression
where the default "external" traffic port was set to a VIP
when using puppet. We should not ever specify a VIP to be used
for the actual machine IPs (VIPs are only guaranteed to
work once the load balancer is running).

Also, This doesn't match the non-puppet case.
