Add support for remote Postgres databases

[peter-evans]

Add support for remote Postgres database via environment variables. The environment variables would need to set CONST_Database_DSN in local.php.

@define('CONST_Database_DSN', 'pgsql://@/nominatim'); // <driver>://<username>:<password>@<host>:<port>/<database>

Full list of defaults for Nominatim's settings here.

Would also need an environment variable flag to disable/enable building a new graph in docker-entrypoint.sh.

Hi @Asshad. I don't have working code for this feature yet.
