Use a $datasource variable in the Grafana dashboard.

Currently, each panel in the Grafana dashboard uses a hardcoded datasource uid of datasource. In our Grafana, we use Prometheus. This means that the dashboard doesn't work unless we manually modify each panel. If the dashboard used a variable instead and it didn't match our instance, we could simply pick from the dropdown.

The delivered Rancher dashboards use a template variable like this:

  "templating": {
    "list": [
      {
        "current": {
          "text": "Prometheus",
          "value": "Prometheus"
        },
        "hide": 0,
        "label": "Data Source",
        "name": "datasource",
        "options": [],
        "query": "prometheus",
        "refresh": 1,
        "regex": "",
        "type": "datasource"
      }
    ]
  }

Each panel then just references the $datasource variable.
