Code Issues Proposed changes

Convert role to use a common systemd service role 

This removes the systemd service templates and tasks from this role and
leverages a common systemd service role instead. This change removes a
lot of code duplication across all roles all without sacrificing features
or functionality. The intention of this change is to ensure uniformity and
reduce the maintenance burden on the community when sweeping changes are
needed.

The systemd journal would normally be populated with the standard out of
a service however with the use of uwsgi this is not actually happening
resulting in us only capturing the logs from the uwsgi process instead
of the service itself. This change implements journal logging in the
service config, which is part of OSLO logging.

OSLO logging docs found here: <https://docs.openstack.org/oslo.log/3.28.1/journal.html>

A new variable `cinder_environment_overrides` has been added to ensure
the correct PATH is set for cinder services.

This reverts commit b219b90536.

- The log path, ``/var/log/cinder`` is no longer used to capture service
logs. All logging for the cinder service will now be sent directly to the
systemd journal.
