Prometheus Helm release name doesn't match

[jordifebrer]

BUG REPORT

What happened:
The release name prom on Prometheus helm installation details on this page: https://docs.litmuschaos.io/docs/integrations/prometheus/#prometheus-community-version-helm---kube-prometheus-stack-with-pod-monitor doesn't match with the provided PodMonitor release name prometheus-stack.

The service discovery never discover the podmonitor because is looking for a podmonitor with a label release: prom instead of release: prometheus-stack

What you expected to happen:

helm install prom prometheus-community/kube-prometheus-stack --namespace monitoring

should be

helm install prometheus-stack prometheus-community/kube-prometheus-stack --namespace monitoring

How to reproduce it (as minimally and precisely as possible):

1. Run:

helm install prom prometheus-community/kube-prometheus-stack --namespace monitoring

2. Apply the PodMonitor:

apiVersion: monitoring.coreos.com/v1
kind: PodMonitor
metadata:
  name: chaos-exporter-monitor
  namespace: monitoring
  labels:
    release: prometheus-stack
spec:
  selector:
    matchLabels:
      app: chaos-exporter
  namespaceSelector:
    matchNames:
      - litmus
  podMetricsEndpoints:
    - port: tcp
    - interval: 1s
      metricRelabelings:
        - targetLabel: instance
          replacement: 'chaos-exporter-service'

Anything else we need to know?:
I suggest using a release name prometheus-stack with helm install because is following the naming convention used in the rest of the repository instead of changing the release name of the PodMonitor to prom.
