Nomad meta data is not available in nomad discovery records

[Teknoenie]

What's wrong?

When trying to use Grafana Alloy as a discovery agent for Nomad containers, we are finding that any meta block information is not visible from the nomad.discovery targets. Since Alloy is using the Nomad HTTP API, it would be great if there was an option to pass meta = true to the nomad.discovery module so that we can do something with that data.

Steps to reproduce

/* Nomad discovery */
discovery.nomad "nomad_discovery" {
server = "${SERVER}"
bearer_token = "${TOKEN}"
refresh_interval = "10s"
}

/* Prometheus Nomad node metrics scraper */
prometheus.scrape "nomad_scraper" {
targets = discovery.nomad.nomad_discovery.targets
extra_metrics = true
forward_to = [prometheus.remote_write.mimir.receiver]
job_name = "nomad_metrics"

scrape_interval = "10s"

tls_config {
insecure_skip_verify = true
}
}

Look at the output and you find that there is no Nomad based meta block info
