Subject: [PATCH] feat: add ability to import Grafana dashboards (#1700)

* feat: add ability to import Grafana dashboards

* chore: remove unnecessary file

* chore: more 9XX support

* chore: some more hacks

* chore: update deps

* chore: arrange equal spaced widgets instead of inheriting from grafana
