Use new method from Google : stackdriver-prometheus-sidecar

[tpoindessous]

Hi

I use your tutorial and it's working fine.

But you use stackdriver-prometheus image which seems to be obsolete and now superceded by stackdriver-prometheus-sidecar

https://github.com/Stackdriver/stackdriver-prometheus is read-only
https://github.com/Stackdriver/stackdriver-prometheus-sidecar

Could you please update your tutorial to use new method ?

It seems that metrics are now read from external/prometheus
Reference doc : https://cloud.google.com/monitoring/kubernetes-engine/prometheus

Thanks !
