[BUG] AMA pods don't use recommended Kubernetes labels

[illrill]

Describe the bug

The AMA pods do not make use of stable and recommended Kubernetes labels. This has several downsides:

• They appear as "Unknown App" in Hubble UI
• They are more difficult to select in network policies
• They are more difficult to select with kubectl
• It looks unprofessional

Expected behavior

Use consistent pod labels as per Kubernetes recommendations and best practices. For example:

• ama-metrics
  • app.kubernetes.io/name: ama-metrics
  • app.kubernetes.io/part-of: azure-monitor
  • app.kubernetes.io/component: prometheus-collector
• ama-metrics-node
  • app.kubernetes.io/name: ama-metrics-node
  • app.kubernetes.io/part-of: azure-monitor
  • app.kubernetes.io/component: node-collector
• ama-metrics-operator-targets
  • app.kubernetes.io/name: ama-metrics-operator-targets
  • app.kubernetes.io/part-of: azure-monitor
  • app.kubernetes.io/component: target-allocator
• ama-metrics-ksm
  • app.kubernetes.io/name: ama-metrics-ksm
  • app.kubernetes.io/part-of: azure-monitor
  • app.kubernetes.io/component: kube-state-metrics
