CP 24028 add insights controller scape config

[josephbarnett]

Description

• CP-24028: add scrape target for insights container
• CP-22734: Bump insights image release version
• Enhance README for helm repo management
• Add release note for next beta version
• Update release process for customer version numbers in betas

Testing

1. Deploy small cluster

   apiVersion: eksctl.io/v1alpha5
   kind: ClusterConfig
   
   metadata:
     name: aws-cirrus-jb-insights-cluster
     region: us-east-2
   
   iam:
     withOIDC: true
   
   addons:
     - name: vpc-cni
       version: latest
     - name: kube-proxy
       version: latest
     - name: coredns
       version: latest
   
   nodeGroups:
     - name: ng-1
       instanceType: t3.small
       desiredCapacity: 2
       volumeSize: 20
       amiFamily: Bottlerocket

   eksctl create cluster -f insights-cluster.yaml

2. Deploy cert manager

   kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.16.2/cert-manager.yaml

3. Create configuration for overrides

    cloudAccountId: |-
      975482786146
    clusterName: aws-cirrus-jb-insights-cluster
    region: us-east-2
    existingSecretName: cloudzero-api-key
   
    server:
      args:
        - --config.file=/etc/config/prometheus/configmaps/prometheus.yml
        - --web.enable-lifecycle
        - --web.console.libraries=/etc/prometheus/console_libraries
        - --web.console.templates=/etc
   
    insightsController:
      enabled: true
      server:
        image:
          tag: dev-ff25286d1f1e6625bde33236d0ad639874cf5d4a
      labels:
        enabled: true
        patterns:
          - '.*'
      annotations:
        enabled: false
        patterns:
          - '.*'
   
    cert-manager:
      # -- Your cluster may already have cert-manager running, in which case this value can be set to false.
      enabled: false

4. Deploy the Agent

   helm upgrade --install cloudzero-agent . -f override.yaml

5. Forward the prometheus UI port

   kubectl port-forward svc/cloudzero-prometheus-server 9090:9090
