We will need to setup an VPN to be able to access fox in its new
location, so for now we simply remove the IPMI monitoring.

Fox should reply once the machine is connected to the UPC network.
Monitoring also the gateway and UPC anella allows us to estimate if the
whole network is down or just fox.

These sensors are part of their air quality measurements, which just
happen to be very close to our server room.

Allows us to track ambient temperature changes and estimate the
temperature delta between the server room and exterior temperature.
We should be able to predict when we would need to stop the machines due
to excesive temperature as summer approaches.

Allows us to see which derivations are being built in realtime. It is a
bit of a hack, but it seems to work. We simply look at the environment
of the child processes of nix-daemon (usually bash) and then look for
the $name variable which should hold the current derivation being
built. Needs root to be able to read the environ file of the different
nix-daemon processes as they are owned by the nixbld* users.

Now that we have more space, we can extend the retention time to 5 years
to hold the monitoring metrics. For a year we have:
# du -sh /var/lib/prometheus2
13G /var/lib/prometheus2
So we can expect it to increase to about 65 GiB. In the future we may
want to reduce some adquisition frequency.

Prevents the "iptables: Chain already exists." error by making sure that
we don't leave any chain on start. The ideal solution is to use
iptables-restore instead, which will do the right job. But this needs to
be changed in NixOS entirely.

Ensure that all hut users have a paste directory in /ceph/p owned by
themselves. We need to wait for the ceph mount point to create them, so
we use a systemd service that waits for the remote-fs.target.

Instead of using multiple tunels to forward all our services to the VM
that serves jungle.bsc.es, just use nginx to redirect the traffic from
hut. This allows adding custom rules for paths that are not posible
otherwise.

Starting with GitLab 16, there is a new mechanism to authenticate the
runners via authentication tokens, so use it instead. Older tokens and
runners are also removed, as they are no longer used.
With the new way of managing tokens, both the tags and the locked state
are managed from the GitLab web page.

To accomodate the raccoon knights workstation, some of the configuration
pulled by m/common/main.nix has to be removed. To solve it, the xeon
specific parts are placed into m/common/xeon.nix and only the common
configuration is at m/common/base.nix.

The main website of the BSC is failing every day around 3:00 AM for
almost one hour, so it is not a very good target. Instead, google.com is
used which should be more reliable. The same robots.txt path is fetched,
as it is smaller than the main page.

As all other HTTPS probes pass through the opsproxy01.bsc.es proxy, we
cannot detect a problem in our proxy or in the BSC one. Adding another
target like bsc.es that doesn't use the ops proxy allows us to discern
where the problem lies.
Instead of monitoring https://www.bsc.es/ directly, which will trigger
the whole Drupal server and take a whole second, we just fetch robots.txt
so the overhead on the server is minimal (and returns in less than 10 ms).
