The StartLimitBurst and StartLimitIntervalSec options belong to the
[Unit] section, otherwise they are ignored in [Service]:
> Unknown key 'StartLimitIntervalSec' in section [Service], ignoring.
When using [Unit], the limits are properly set:
apex% systemctl show power-policy.service | grep StartLimit
StartLimitIntervalUSec=10min
StartLimitBurst=10
StartLimitAction=none

In all machines, as soon as we recover the power, turn the machine back
on. We cannot rely on the previous state as we will shut them down
before the power is cut to prevent damage on the power supply
monitoring circuit.

The UPC has different dates for the yearly power cut, and Fox can
recover properly from a power loss, so we don't need to have it turned
off before the power cut. Simply disabling the timer is enough.

The cudainfo program checks that we can initialize the CUDA RT library
and communicate with the driver. It can be used as standalone program or
built with cudainfo.gpuCheck so it is executed inside the build sandbox
to see if it also works fine. It uses the autoAddDriverRunpath hook to
inject in the runpath the location of the library directory for CUDA
libraries.

This allows running derivations which depend on cuda runtime without
breaking the sandbox. We only need to add `requiredSystemFeatures = [ "cuda" ];`
to the derivation.

Access internal hosts via apex proxy. From the compute nodes we first
open an SSH connection to apex, and then tunnel it through the HTTP
proxy with netcat.
This way we allow reaching internal GitLab repositories without
requiring the user to have credentials in the remote host, while we can
use multiple remotes to provide redundancy.
