some services don't deploy cleanly on bare_metal if there are other services on same host

[Darren Birkett]

Example:

Try and deploy cinder-volume service on bare_metal, on the same host as nova compute (which has nova and neutron installed on the bare metal host already). When you run the plays. It will try and install the cinder sha, using the neutron service name:

Note how it is trying to install neutron_22ad32603ca7fd9a6e8f66f36bb52350a6064558/, rather than cinder_22ad32603ca7fd9a6e8f66f36bb52350a6064558/

This is how I got around the issue (including inventory/group_vars/cinder_all.yml explicitly ensures that the service name that's used in the container common play is set to cinder):

Marking as invalid for Kilo/Master as the vars structures were changed in Kilo which negates this issue.

    include cinder_all group vars file in cinder-* playbooks

    If we don't explicitly set cinder as the service name, and then try and
    install cinder onto a host that already has other services (such as
    when you're installing cionder-volume ontobare metal where other
    services exist), then the cinder plays get run with 'something else' as
    the service name. i.e., if installing ciner-volume onto a compute host
    that has nova and neutron, then the cinder plays get run with neutron
    as the service name.

    This commit explicitly includes the cinder_all groups vars file, which
    itself explicitly sets cinder as the service name.
