python-cinder: uprev to latest stable/pike

Requires the introduction of python-oauth2client and
python-google-api-python-client packages/recipes. As with other
openstack component uprev's we move some of the initialization from
the first run scripts to the cinder-init.service which is run on first
boot. This allows for someone to disable the default configuration by
not including the cinder-init package in their image.

The initialization is done following the guide at:

At this point we have cinder up and running, which we can verify using
the "openstack volume service list" command.

root@controller:~# openstack volume service list
+------------------+----------------------+------+---------+-------+----------------------------+
| Binary           | Host                 | Zone | Status  | State | Updated At                 |
+------------------+----------------------+------+---------+-------+----------------------------+
| cinder-backup    | controller           | nova | enabled | down  | 2018-04-30T15:31:08.330770 |
| cinder-volume    | controller@nfsdriver | nova | enabled | down  | 2018-04-30T15:31:10.477678 |
| cinder-scheduler | controller           | nova | enabled | down  | 2018-04-30T15:31:10.653041 |
+------------------+----------------------+------+---------+-------+----------------------------+

We will have to adjust the configuration for a compute node but at
this point we are concentrating on the initial configuration for the
controller image.
