Use <project>_install_type instead of kolla_install_type
to set python_path. For example, general kolla_install_type
is 'binary', but user wants to deploy Horizon from 'source'.
Horizon templates still use python_path=/usr/share/openstack-dashboard,
it is wrong.

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.
