‘OpenStack Usage Efficiency’ Grafana dashboard

Implemented the OpenStack Usage Efficiency dashboard for Grafana that provides information about requested (allocated) CPU and memory usage efficiency on a per-project and per-flavor basis.

This dashboard aims to identify flavors that specific projects are not effectively using, with allocations significantly exceeding actual usage. Also, it evaluates per-instance underuse for specific projects.
