Hello, awesome prom people 👋

I started testing the Prometheus agent and would like to use consul to discover that specific host `metric_path` and other data. However, I am having trouble filtering it out properly. My `consul_sd_configs:`

```auto
    - server: "<consul_server>"
      token: "<token>"
      tags:
        - exporter
      allow_stale: false
      refresh_interval: 5m
  relabel_configs:
    - source_labels:
      - __meta_consul_service
      target_label: job
    - source_labels:
      - __meta_consul_node
      target_label: instance
.....

```

The thing is that ` __meta_consul_node` can not be used like `__ meta_consul_metadata_<key>` and as I do not have hostname or fqdn (which I need) in metadata, so `node_meta` is a no go here (?), my question - is it possible to somehow use `__meta_consul_node` to filter out that specific node?

I ended up adding fqdn to consul metadata ✅
