[Tempo] - Networkpolicies in the grafana Tempo helm charts

[drisbee]

Expected Behavior

It should be possible in the values file to configure the Networkpolicy, so that somebody can enable it and the networkpolicies are automatically created for all the internal components of grafana tempo.

Current Behavior

When running kube-score on the grafana-tempo chart I see this error:

[CRITICAL] Pod NetworkPolicy
        · The pod does not have a matching NetworkPolicy
            Create a NetworkPolicy that targets this pod to control who/what
            can communicate with this pod. Note, this feature needs to be
            supported by the CNI implementation used in the Kubernetes cluster
            to have an effect.

Possible Solution

Creating a boolean value that you can set to true so that all the networkpolicies are created for all the internal components.

Steps to Reproduce

1. In the chart folder run the kube-score command
2. helm template . | kube-score score -

Context (Environment)

We want to use kube-score in our pipelines to enforce best practices
