This change fixes the following issues:
- wrong sudoers command
- bad arguments for ceilometer-upgrade
- removes the deprecated storage backends,
as per https://review.openstack.org/#/c/512700/
Please note that due to the aforementioned issues, ceilometer
deployment was failing. I first encountered this issue when
attempting to upgrade from pike to queens.
