Abstract storage configuration section to load different database backend drivers. so we can keep supporting elasticsearch for a while after moving to oslo.db also this will help in adding API v2 as the elasticsearch driver will be changed. Each db driver will register it's configuration on the run time. Change-Id: Ie861e569f4add783c6f580cd0c08ed0fb3440151
