with kubernetes/puppet deployment, we are mounting /etc/puppetlabs/code
into a PVC. g10k hardlinks. therefore, we need the g10k cache in the

- set cachedir to a hardlink compat path for kubernetes
update the source to use the endpoint via haproxy with letsencrypt
certificates. this will make it simpler to manage trust in externally
sources containers used for puppet/k8s integration
- use git.unkin.net url for unkin origin
