chore: OpenFaas function to get metrics from Kubernetes

Keith Grootboom requested to merge keith/get-cluster-metrics into main

Description

Adds an OpenFaas function to generate a report containing the resource usage per namespace. The report includes:

  • cpu minutes used
  • memory used
  • how many VMs the above is equivalent to.

Testing instructions

I've set up the service at https://openfaas.kgcluster.opencraft.hosting/ui/. Password can be found in vault path: shared/openfaas-ingresskgcluster

It can be tested with the following URLs:

curl --insecure -u admin:pass https://openfaas.kgcluster.opencraft.hosting/function/usage-reporter
curl --insecure -u admin:pass https://openfaas.kgcluster.opencraft.hosting/function/usage-reporter -H "Content-Type: application/json" --request POST --data '{"provider": "k8s-metrics"}'
curl --insecure -u admin:pass https://openfaas.kgcluster.opencraft.hosting/function/usage-reporter -H "Content-Type: application/json" --request POST --data '{"provider": "prometheus": "timestamp": "2022-10-01"}'
