cinder-backup: enable swift backend

Modify cinder config file allows cinder-backup
to be able to use swift as backend for
storing cinder backup volume on Swift cluster.

Also add variable CINDER_BACKUP_BACKEND_DRIVER
which allows setting default cinder backup backend
driver.  Right now set it to Swift.
