[one-users] Using CloudInit for contextualization

[Javier Fontan]

Unfortunately the current version of cloud-init does not load new
network parameters after they are configured in some distributions.
There is a ticket to track that problem [1]

The documentation gives some ideas on how to overcome this [2]:

--8<------
The current version of cloud-init configures the network before
running cloud-init configuration. This makes the network configuration
not reliable. Until a new version that fixes this is released you can
add OpenNebula context packages or this user data to reboot the
machine so the network is properly configured.
