all plugins should call __init__ in db_base_plugin for db.configure

[Aaron Rosen]

Currently each plugin calls db.configure() within the plugin's __init__ class or defines an initialize() method that's sole job is to call this method. Instead we should just call the super method of the db_base_plugin so that it calls this for us automatically.

Note: the only reason why I'm making this change is that I want to add something to the __init__() class of the db_base_plugin that's needed for the nova-event-callback blueprint and adding it in the base class of init looks to be the best place.

    Plugins should call __init__ of db_base_plugin for db.configure

    Currently each plugin calls db.configure() within the plugin's __init__
    class or defines an initialize() method that's sole job is to call this
    method. Instead we should just call the super method of a plugin so that
    db.configure() is called for us out of the db_base_plugin class.

    Note: the only reason why I'm making this change is that I want to add
    something to the __init__() class of the db_base_plugin that's needed for
    the nova-event-callback blueprint and adding it in the base class of init
    looks to be the best place.
