postgres_exporter Add TLS support for Prometheus communication

Please add TLS support for Prometheus communication like it already was done for : node_exporter

That's a useful answer
Without any help

IT would be great if this also included basic user authentication along with TLS - again in line with node exporter - see https://developpaper.com/add-authentication-to-prometheus-node-exporter/
