Issue:
sabnzbd_warnings metric suggestions
Testing v1.3.0:

* Regarding `sabnzbd_warnings` metric.  Assuming this is the equivalent of `radarr_system_health_issues` / `sonarr_system_health_issues` / `lidarr_system_health_issues` then suggest it be renamed such as `sabnzbd_system_health_issues` for consistency.

* Secondly with `sabnzbd_warnings` it returns `target="http://sabnzbd...:80"` instead of `url="http://sabnzbd...:80"`. Which causes it to be rendered differently:

Vs how something like Radarr renders:

**Description of the change**

Two changes in this PR:
1. Because SabnzbD came from `prometheus-sabnzbd-exporter`, it was using `target` as the common static label, rather than `url` as the rest of `exportarr` does. This PR unifies these labels.
2. In `#151`, it was pointed out that the `warnings` metric on the surface appears similar to the `system_health` metrics in `*arr`. This metric is very different -- it contains a count of warnings from the queue, rather than being system wide. It also only gives a raw count, rather than returning an info metric with the message attached. This PR renames the metric to `queue_warnings` to help distance the metric from the system health metrics in Arr. The Help message can stay, as it was already clear on the specificity to the queue:
```
# HELP sabnzbd_queue_warnings Total Warnings in the SabnzbD instance's queue
```

**Benefits**

Described above.

**Possible drawbacks**

Users who are already leveraging the `target` label in dashboards or alerts will need to adjust to use `url` instead. I think given the newness of the sabnzbd sub command, this should be a small group.
