Instead of having a pretty restrictive module based api for saving logbook objects it is much more friendly and extensible to move toward a more ceilometer-influenced engine and connection based storage backend using stevedore to do the backend loading instead of a custom registration/fetching mechanism. This allows us to provide a base object oriented backend api that can be easily inherited from to allow for customized & pluggable backend storage modules.
