Fix and Update Lab 7 - Add Monitoring to an Azure Kubernetes Service Cluster

[mathieu-benoit]

Need contributions and help here, anyone would like to jump on this one?

Since PR #108 and like explained there, "Lab 7 - Add Monitoring to an Azure Kubernetes Service Cluster" is not working well now. Data are not properly populated in Grafana dashboards.

So far, here are what have been found and the thoughts on that so far:

• The lab is using old versions:
  • Prometheus Helm chart 4.6.13 (12/2017), furthermore Prometheus itself changed from 1 to 2 with breaking changes.
  • Grafana Helm chart 0.5.1 (12/2017)
• For this specific Hackfest content, do we want to use the monitoring aks addon instead (Azure Monitor)? Could be enabled at creation or afterward, and it's pretty straightforward - https://docs.microsoft.com/en-us/azure/monitoring/monitoring-container-health
• We are seeing more and more Prometheus Operator...

@mathieu-benoit : There is a forked version of the GBB repo where we updated the Monitoring stuff to work with RBAC enabled cluster. There is a minor change to set RBAC to true in prometheus-configforhelm.yaml. The screenshots are also updated.
