Pillar / config used

prometheus:
  pkg:
    use_upstream_repo: true
    use_upstream_archive: false
    component:
      prometheus:
        service:
          args:
            web.listen-address: 192.168.1.1:9191
            enable-feature: remote-write-receiver

Bug details

Describe the bug

I trying to enable remote write receiver, and set custom listen address and port. I took example from pillar.example and fill needed values, applied changes without errors, but as result - my config is not applied.

Changes to other part of pillar, for example, scrape_interval: 16s, applied successfully.

Steps to reproduce the bug

1. Add to the pillar in section pkg.component.prometheus.service.args some args, eg:

          args:
            web.listen-address: 192.168.1.1:9191
            enable-feature: remote-write-receiver

2. Apply changes via state.apply
3. See that prometheus process don't receive this arguments. File /lib/systemd/system/prometheus.service also don't contain my custom args.

Expected behaviour

Custom args must be applied via adding to /lib/systemd/system/prometheus.service file or via some other way.
