This commit adds an assertion that checks that either `configFile` or
`configuration` is configured for alertmanager. The alertmanager config
can not be an empty attributeset. The check executed with `amtool` fails
before the service even has the chance to start. We should probably not
allow a broken alertmanager configuration anyway.
This also introduces a test for alertmanager configuration that piggy
backs on the existing prometheus tests.
The nixos test is a bit misleading, as the given nginx configuration
would always cause gitlab to redirect to localhost, which is clearly not
what you want in a production setup.
Instead we now enable services.nginx.recommendedProxySettings,
curl against http://gitlab, and assure we get redirected to that same
hostname, too.
Previously I got the following error message:
```
error: opening file '/home/ma27/Projects/nixpkgs/nixos/modules/installer/default.nix': No such file or directory
```

Mininet (https://github.com/mininet/mininet) is a popular network emulator that
glues several components such as network namespaces, traffic control
commands into a set of python bindings. It is then "easy" to describe a
topology and run experiments on it.
The default of systemd is to kill the
the whole cgroup of a service. For slurmd
this means that all running jobs get killed
as well whenever the configuration is updated (and activated).
To avoid this behaviour we set "KillMode=process"
to kill only slurmd on reload. This is how
slurm configures the systemd service.

Commit f1987fb58f57828944ca822bbb39b3de87f01863 renamed colemak/en-latin9 to
colemak/colemak, but the keymap test wasn't adjusted to refer to the new path.
previously one of the tests would fail with

Shortening the test name fixes the issue.
Cloudstack images are simply using cloud-init. They are not headless
as a user usually have access to a console. Otherwise, the difference
with Openstack are mostly handled by cloud-init.
This is still some minor issues. Notably, there is no non-root user.
Other cloud images usually come with a user named after the
distribution and with sudo. Would it make sense for NixOS?
Cloudstack gives the user the ability to change the password.
Cloud-init support for this is imperfect and the set-passwords module
should be declared as `- [set-passwords, always]` for this to work. I
don't know if there is an easy way to "patch" default cloud-init
configuration. However, without a non-root user, this is of no use.
Similarly, hostname is usually set through cloud-init using
`set_hostname` and `update_hostname` modules. While the patch to
declare nixos to cloud-init contains some code to set hostname, the
previously mentioned modules are not enabled.
