Fix for `Failed to upgrade legacy queries Datasource ${DS_PROMETHEUS} was not found`
Problem:
When we try to manually import Grafana dashboards, we have the following error `Failed to upgrade legacy queries Datasource ${DS_PROMETHEUS} was not found` when we open the dashboard once imported.
Solution:
Add this to each dashboard:
```yaml
{
"hide": 0,
"label": "datasource",
"name": "DS_PROMETHEUS",
"options": [],
"query": "prometheus",
"refresh": 1,
"regex": "",
"type": "datasource"
},
```
It also fix dashboards that were not working with [kube-prometheus-stack helm chart](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack)
Validation
Fixes [10873](https://github.com/linkerd/linkerd2/issues/10873)

Using Grafana with Linkerd
You can install Grafana in various ways, like using the Grafana official Helm chart, or the Grafana Operator. Hosted solutions are also available, like Grafana Cloud.
The file grafana/values.yaml provides a default Helm config for the Grafana
official Helm
chart, which
pulls the Linkerd dashboards published at
https://grafana.com/orgs/linkerd/dashboards.
You can install the chart like this:
helm repo add grafana https://grafana.github.io/helm-charts
helm install grafana -n grafana --create-namespace grafana/grafana \
-f https://raw.githubusercontent.com/linkerd/linkerd2/main/grafana/values.yaml
Please make sure to update the entries in grafana/values.yaml before using the
file; in particular:
- auth and log settings under
grafana.ini datasources.datasources.yaml.datasources[0].urlshould point to your Prometheus service
The other installation methods can easily import those same dashboards using
their IDs, as listed in grafana/values.yaml.
In order to have the Linkerd Viz Dashboard show the Grafana icon there where
relevant, and have it link to the appropriate Grafana dashboard, make sure you
have a proper location set up in the grafana.url setting in Linkerd Viz's
values.yaml.
Granting access
As of linkerd stable-2.13.0 (or edge-23.1.1), the access to Linkerd Viz'
Prometheus instance has been restricted through the prometheus-admin
AuthorizationPolicy, granting access only to the metrics-api ServiceAccount.
In order to grant access to Grafana, you need to add an AuthorizationPolicy
pointing to its ServiceAccount. You can apply
authzpolicy-grafana.yaml which grants
permission for the grafana ServiceAccount.
Note to developers
The grafana/dashboards directory contains the same dashboard definitions
published under https://grafana.com/orgs/linkerd. Please keep them in sync when
making any changes. After logging into grafana.com (using the linkerd account),
the dashboards can be managed under Org Settings -> My Dashboards.
