This PR combines all my cleanups and fixes. It also includes the changes of PR https://github.com/NVIDIA/dcgm-exporter/pull/240 by @Levi080513
Use PromQL aggregations to take MIG subdevices into account (see #353)
Update all panels to use Timeseries panels (instead of deprecated Graph)
Switch from instance to Hostname to select individual systems to avoid

Use DCGM_FI_DEV_FB_FREE instead of DCGM_FI_DEV_GPU_TEMP to also cover vGPU (PR #240)
Use DCGM_FI_PROF_GR_ENGINE_ACTIVE to determine utilization to cover MIG (and vGPU)
