Add script for loading prometheus snapshots, improve grafana

1. Add scripts for loading prometheus snapshots locally
2. Improve Grafana dashboards for performance tests
3. Improve Grafana dashboards management (now there's one configmap
      for all dashboards and to add new dashboard only needed change
      is adding new json file in grafana/dashboards directory)
4. Add prometheus job for scraping node metrics and add deployment
      yaml for node exporter
