This just updates upstart jobs to the new single binary approach.

The new classes 'DataSourceNoCloud' and 'DataSourceNoCloudNet'
implement a way to get data from the filesystem, or (very minimal)
data from the kernel command line.  This allows the user to seed data to
these sources.

There are now 2 "cloud-init" jobs, cloud-init-local that runs on 
  mounted MOUNTPOINT=/
and 'cloud-init' that runs on 
  start on (mounted MOUNTPOINT=/ and net-device-up IFACE=eth0 and
     stopped cloud-init-local )

The idea is that cloud-init-local can actually function without network.

The last thing in this commit is "uncloud-init".
This tool can be invoked as 'init=/usr/lib/cloud-init/uncloud-init'
It will "uncloudify" things in the image, generally making it easier
to use for a simpler environment, and then it will exec /sbin/init.

Some changes were rushed in prior to lucid beta that didn't get pulled
back into the upstream release.  I'm pulling those in here.
