Change swift ssl port

Using our typical ssl port scheme of "replace first digit with 13",
the swift port of 8080 conflicts with the nova novnc port of 6080
(both end up on 13080).  In the puppet-tripleo loadbalancer config
we chose to move swift to 13808, so this change updates
os-cloud-config to match.
