This commit enables alerting in Kraken based on the Prometheus queries defined
by the user and modifies the return code of the run to determine pass/fail for
the run.
This commit:
- Enables Kraken to leverage kube-burner to scrape metrics from
Prometheus and index them into Elasticsearch. This way we can
take a look at the metrics in Grafana long term even after the
cluster is terminated.
- Enables separation of operations based on distribution with
OpenShift as the default option. One of the use cases is to
capture Prometheus instance details as it's installed by default
while it's optional for Kubernetes.
