Grafana dashboard: Grafana-Prometheus-Node_Exporter_Host_Metrics_Dashboard
Description: This is a simple Grafana Dashboard to display Host Metrics such CPU, Memory, DISK IO, Load Average, collected using the Node Exporter

A copy of 10283, with a fixed bug: if node-exporter pod was redeployed, original dashboard returned an error in system uptime field about multiple series returned, also if node was rebooted recently, it could return the same error.
```
- time() - node_boot_time_seconds{instance=~"$node"}
+ time() - (max by (instance) (node_boot_time_seconds{instance=~"$node"}))
```
