[one-users] ubuntu 14.04 as image - no network on first boot

I've updated the debian packages with the ip flush command sent by Stefan
(thanks!). Now it seems to work even when an IP was previously configured
in the interfaces file. This will make the context scripts more resilient
when you save a disk without cleaning the interfaces file.

If there are no major bugs with the new package this will be the one linked
in the documentation.
ML, the source of the context packages in the OpenNebula repository [1]. We
usually put the created packages in the files section of the development
web pages [2] and link them in the documentation [3].
