cloud.cfg: move to a template. setup.py changes along the way.
Here we move the config/cloud.cfg to be rendered as a template. That allows us to maintain deltas between distros in one place. Currently we use 'variant' variable to make decisions. A tools/render-cloudcfg is provided to render the file. There were changes to setup.py, MANIFEST.in to allow us to put all files into a virtual env installation and to render the cloud-config file in 'install' or 'bdist' targets. We have also included some config changes that were found in the redhat distro spec. * include some config changes from the redhat distro spec. The rendered cloud.cfg has some differences. Ubuntu: white space and comment changes only. Freebsd: - whitespace changes and comment changes - datasource_list definition moved to be closer to 'datasource'. - enable modules: migrator, write_files - move package-update-upgrade-install to final. The initial work was done by Josh Harlow.
