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.

device names presented in the metadata service may not be what the kernel
has named them. This can be for more than 1 reason. But some examples:
- device is virtio, metadata named 'sd'
- device is xvdX, metadata named sd
Those are the two situations that are covered here. More complex, but
not covered are possibly:
- metadata service named device 'sda1', but it should actually be 'vdb1'

if user data is of type text/cloud-boothook, or begins with
#cloud-boothook, then assume it to be code to be executed.
Boothooks are a very simple format. Basically, its a one line header
('#cloud-config\n') and then executable payload.
The executable payload is written to a file, then that file is executed
at the time it is read. The file is left in
/var/lib/cloud/data/boothooks
There is no "first-time-only" protection. If running only once is
desired, the boothook must handle that itself.

This logging infrastructure in cloudinit:
- uses python logging
- allows user supplied config of logging.config.fileConfig format to be
supplied in /etc/cloud/cloud.cfg or in cloud_config by user data.
- by default, tries to use syslog, if that is not available, writes directly to
/var/log/cloud-init.log (syslog will not be available yet when cloud-init
runs)
- when using syslog, the doc/21-cloudinit.conf file provides a rsyslogd
file to be placed in /etc/rsyslog.d/ that will file [CLOUDINIT] messages
to /var/log/cloud-init.log

Also
- adds some debugging information when its waiting
- add 'uptime' printout on initial cloud-init invocation
