Fix cinder-api ubuntu binary

This changes moves cinder-api to make use of apache to launch
its processes.
Ubuntu binary removed support in Ocata for cinder-api system
services [1].
At this moment cinder in Ocata branch is not working at all
due this issue.
This changes aims to fix cinder in master only for ubuntu binary
with the purpose of make a clean backport to stable/ocata without
do any other change on the backport process.

A follow up change will migrate other OS/install_type to make use of
Apache but only changing master branch.
