Comment 3 for bug 2049762

I guess this comment chain is the culprit:

https://review.opendev.org/c/openstack/kolla-ansible/+/882893/comments/bb24d1f0_252d8b74

to quote it:

myself:

> question, mainly for mnasiadka:

> should we add the cinder patch to all other services in this patch also?

> That would mean validating service tokens for every service.

> We could maybe also argue to split this work up in a second/more changesets.

> I have a slight preference to split this up to not let this security bugfix wait for much longer.

> What do you think?

mnasiadika:

> I think we should split the rest, it doesn't seem to be required now.

then in patchset 4:

https://review.opendev.org/c/openstack/kolla-ansible/+/882893/3..4/ansible/roles/cinder/templates/cinder.conf.j2

we have:

```
# TODO(mnasiadka): Work out if that's the desired approach or should we add service role to nova user
service_token_roles = admin

then in patchset 6 the comment got removed:

https://review.opendev.org/c/openstack/kolla-ansible/+/882893/5..6/ansible/roles/cinder/templates/cinder.conf.j2

I didn't comment on that because I thought mnasiadka did indeed had checked that this was necessary.
