Example for grafana does not work

[iam-veeramalla]

Describe the bug The example available for Argo CD with grafana does not seem to work. Operator is running into the error state. Example: https://raw.githubusercontent.com/argoproj-labs/argocd-operator/master/examples/argocd-route.yaml

apiVersion: argoproj.io/v1alpha1
kind: ArgoCD
metadata:
  name: example-argocd
  labels:
    example: route
spec:
  grafana:
    enabled: true
    route:
      enabled: true
  prometheus:
    enabled: true
    route:
      enabled: true
  server:
    route:
      enabled: true

To Reproduce Steps to reproduce the behavior:

1. Install the operator from Operator Hub or make run.
2. Create Argo CD Instance with grafana and openshift route as mentioned above.
3. Verify that the Argo CD workloads are not created and operator throws the below error.

I am experiencing this issue as well. After looking at it, it seems the error comes from this line. I cannot find anything that would create the /var/lib/grafana/templates directory or populate any .tmpl files. I looked through the git blame and it doesn't look like anything has changed since the code was introduced.

Is there a missing configuration option?

If u start Prometheus Operator in local-machine (not container) - need to copy files from directory grafana to /var/lib/grafana like it's do in DockerFile.

Or use environment variable GRAFANA_CONFIG_PATH to change dir path from /var/lib/grafana to <PROJECT_PATH>/grafana

Of change ArgoCDDefaultGrafanaConfigPath in common/defaults
