Expost postgres cluster

Expose the postgres cluster outside of the Kubernetes cluster
Give myself the option of connecting to postgres from my own machines,
so that I can hopefully leverage the improved performance
Update some file linting issues in Nix
Add necessary gitlab keys so it can be updated properly the next time I
deploy to it
Add DNS entries for postgres
Update the configuraiton of Traefik to expose the appropriate ports
