[Feature proposal] Integrate some visualization graphs from another open-source dashboard

Another dashboard for Liqo has been created and it is available here, although it was working with Liqo 0.8: https://github.com/zankro/liqo-dashboard-test
This issues proposes to integrate some of the graphs available in the other dashboards, such as the visualization of the resources taken by Liqo peerings, in this cluster.
