This task is complete when we have a proof-of-concept helm chart ready for beta cluster or production deployment.
* [x] Generate a new, blank helm chart for kartotherian.
* [x] Copy existing deployment [[ https://gerrit.wikimedia.org/r/plugins/gitiles/maps/kartotherian/deploy/+/refs/heads/master/scap/ | config template ]] and variables over to a helm chart.
* [x] Minimize unnecessary customizations. Put configuration directly into the kartotherian-config.yaml file unless it really needs to vary between environments. Standardize the entry point so that defaults can be used.
* [ ] Wire the beta and production, postgis replica database hosts. Should go through a load balancer or round-robin to the replica pool.
* [x] Wire postgres user and password as secrets.
Follow-up: Where should the OSM sync to master postgres be run? Perhaps in a specialized variant of the image and chart?
