This commit introduces a new role that downloads and installs the prometheus community postgres exporter https://github.com/prometheus-community/postgres_exporter. A new credential is added to matrix_postgres_additional_databases that allows the exporter access to the database to gather statistics. A new dashboard was added to the grafana role, with some refactoring to enable the dashboard only if the new role is enabled. I've included some basic instructions for how to enable the role in the Docs section. In terms of testing, I've tested enabling the role, and disabling it to make sure it cleans up the container and systemd role.
