Multiple hosts in a single dashboard

[rwjack]

2.3 is looking great, thank you @ar51an!

I have multiple unbound hosts, so I figure I might document this here in case someone needs it.

Step 1: Add the Unbound Host Variable: (Name, Label, Query Option fields)

Step 2: Set the label in the promtail config:

 - job_name: unbound
    static_configs:
    - targets:
        - localhost
      labels:
        job: unbound
        host: <DESIRED_HOSTNAME_LABEL> #######################
.... SNIP ....

Step 3: Modify the dashboard JSON

Replace all occurences of job=\"unbound\" -> with: job=\"unbound\", host=\"${unbound_host}\"

Make sure to save the dashboard and voila!
