nixos/prometheus-exporters: rewrite and restructure
- prometheus exporters are now configured with
  `services.prometheus.exporters.<name>`
- the exporters are now defined by attribute sets
  from which the options for each exporter are generated
- most of the exporter definitions are used unchanged,
  except for some changes that should't have any impact
  on the functionality.
