Steps to Reproduce the Problem

Install a new AKS cluster as described by README.md

Expected Behavior

The managed grafana should present a dashboard similar to the one existing on the current release longhaul and similar to what is shown on https://docs.dapr.io/operations/observability/metrics/grafana/

Actual Behavior

  1. There is no default dashboard installed
  2. There is no Dapr prometheus datasource installed in managed Grafana by default
  3. Installing the dashboards available on https://github.com/dapr/dapr/tree/master/grafana don't produce the expected result as most of the dependent metrics are not available on the managed Prometheus

Regarding item 3 (missing Prometheus metrics), seems there is a major difference in how Prometheus is configured out of the box (be it the Azure managed one or from a fresh Helm setup) and how it is configured right now in the release clusters. This distinction is also encoded in the grafana dashboards we saved in dapr/dapr, which refer to metrics by names that only exists in the release longaul prometheus setup.

As an example, I am pasting a diff of what one would find in a helm-installed grafana and what we have in release longhaul:

Fix Grafana dashboards.
21b5034 
The current grafana dashboards do not work in a fresh cluster where
prometheus and grafana are installed using helm following Dapr Docs
(see [1], [2]). They refer to metrics that are not available in
such install.

In short, based on bug-report from dapr/test-infra#204, the proposed
fix can be summed by:

```bash
sed -i \
    -e 's/\bkubernetes_name\b/service/g' \
    -e 's/\bkubernetes_namespace\b/namespace/g' \
    -e 's/\bkubernetes_node\b/node/g' \
    -e 's/\bkubernetes_pod_name\b/pod/g' \
    *.json
```

Additionally:

* Removes refresh rates smaller than 1 minute.
* Sets default interval range to 14 days in the past to now
* Sets default template values to match the longhaul clusters.

Fixes dapr#7120
