The module is only enabled on Hut and Eudy because we noticed activity
on the debuginfod service even if no debug session was active.

The /tmp directory was using the SSD disk which is not erased across
boots. Nix will use /tmp to perform the builds, so we want it to be as
fast as possible. In general, all the machines have enough space to
handle large builds like LLVM.

The old runners for the PM gitlab were disabled in configuration in the
last outage, but they remained working until we reboot the node. With
this change we enable the runners for both PM and gitlab.bsc.es.

The target gw.bsc.es doesn't reply to our ICMP probes from hut. However,
the anella hop in the tracepath is a good candidate to identify cuts
between the login and the provider and between the provider and external
hosts like Google or Cloudflare DNS.

These probes check if we can reach several targets via ICMP, which is
not proxied, so they can be used to see if ICMP forwarding is working in
the login node.
In particular, we test if we can reach the Google (8.8.8.8) and
Cloudflare (1.1.1.1) DNS servers, the BSC gateway which responds to ping
only from the intranet and the login node (ssfhead).

The alerts need to contact the slack endpoint, so we add the proxy
environment variables to the grafana systemd service.

By default it was trying to reach the targets using the default gateway,
but since the electrical cut of 2023-10-20, the login node has not
enabled forwarding again. So better if we don't rely on it.

This is done to prevent accidental evaluations where the nixpkgs input
of bscpkgs is still pointing to a different version that the one
specified in the jungle flake. Instead use jungle#bscpkgs.X to get a
package from bscpkgs.
