Implement bootstrapping for custom nova flavors

Previously nova just created default flavors. This patch adds ability to
specify custom flavors in ~/.ccp.yaml.

Also this patch renames job to more general format and moves all default
flavors to defaults.yaml config. Now Jinja loop was moved to service
definition yaml, which create one job per one flavor.

Bootstrapping is enabled by default.
