assets: modify and add grafana dashboards

Move to v1 from v1alpha1

Update to latest kube-state-metrics

Resource pods added to role prometheus-k8s for namespace default. This is required to monitor kube-apiserver.

* *: use jsonnet to generate manifests

* generate Prometheus Operator manifests with jsonnet

* add jsonnet dockenfile for generating with jenkins

grafana chart for kube-prometheus

kube-prometheus: run prometheus-k8s with only those roles it needs

kube-state-metrics needs additional permissions for replicationcontrollers, limitranges, and services (otherwise the API server logs are flooded with RBAC DENY messages)

kube-prometheus: update serviceMonitorSelector

In cleanup commit 9cd05a8c39c6ed03688859de92372d93af5cc6e2 the labels on the ServiceMonitors were changed from k8s-apps to k8s-app. This commit makes the Prometheus selector match that change.
