Antoine Eiche 2858b35100 nova-image: use wget instead of cloud-init (via EC2 API)
The Openstack metadata service exposes the EC2 API. We use the
existing `ec2.nix` module to configure the hostname and ssh keys of an
Openstack Instance.

A test checks the ssh server is well configured.

This is mainly to reduce the size of the image (700MB). Also,
declarative features provided by cloud-init are not really useful
since we would prefer to use our `configuration.nix` file instead.
