The intent is to use the instance struct to hold the connection to the database as well as metadata about the instance. Currently this metadata only includes the version of postgres for the instance which can be used in the collectors to decide what query to run. In the future this could hold more metadata but for now it keeps the Collector interface arguments to a reasonable number.

Please note, the following features are deprecated and may be removed in a future release:
- `auto-discover-databases`
- `extend.query-path`

This exporter is meant to monitor PostgresSQL servers, not the user data/databases. If
you need a generic SQL report exporter https://github.com/burningalchemist/sql_exporter
is recommended.

The signature for creating a collector changed and CI didn't retrigger. Move metrics out of map and into individual vars.

Adds support for the alternate postgres:// prefix in URLs. It's maybe
not the cleanest approach, but works. Hoping I can either get some
pointers on a more appropriate patch, or that we could use this in the
interim to unblock this use-case.
