This is necessary for the NixOS EFI boot machinery to pick up the new
derivation when switching to it, otherwise the machine will not boot
into the newly switched configuration.

Stopgap until we finish b/3, need to deploy some changes on it without
rebooting into newer nixpkgs.

This is a basic grafana running on:
https://monitoring-global-dashboard.k0.hswaw.net/
It contains a data source pointing at the corresponding global victoria
metrics. There's no dashboards, these will be provisioned soon via
jsonnet/grafonnet.

These get scraped by public IP address, which get retrieved via service
discovery in Prometheus (by using the endpoints role on the
default/kubernetes service).
Also drive-by fix cluster prometheus resources - the default
configuration wants at least 3GB of physical memory.

We handwavingly plan on implementing monitoring as a two-tier system:
- a 'global' component that is reponsible for global aggregation,
long-term storage and alerting.
- multiple 'per-cluster' components, that collect metrics from
Kubernetes clusters and export them to the global component.
In addition, several lower tiers (collected by per-cluster components)
might also be implemented in the future - for instance, specific to some
subprojects.
Here we start sketching out some basic jsonnet structure (currently all
in a single file, with little parametrization) and a cluster-level
prometheus server that scrapes Kubernetes Node and cAdvisor metrics.
This review is mostly to get this commited as early as possible, and to
make sure that the little existing Prometheus scrape configuration is
sane.
