Reconfiguration fails as non-root user with ceph enabled due to missing 'become'

[Mark Goddard]

Kolla ansible is now supposed to support remote execution as a non-root user [1]. While trying to modify the CI tests to use a non-root user, it was found that configuration of ceph integration for glance fails with the following error:

TASK [glance : Copying over ceph.conf(s)] **************************************
fatal: [primary]: FAILED! => {
    "msg": "Failed to get information on remote file (/etc/kolla//glance-api/ceph.conf): Permission denied"

This is because some tasks in ceph.yml for glance are missing the 'become' attribute. This issue applies also to other similar ceph.yml and external_ceph.yml files for nova, cinder, gnocchi and manila.

I suspect this didn't fail on the initial deploy due to the recursive owership & permissions change at the end of these files.
