Default CephAnsibleSkipClient to True and CephConfigPath to
/var/lib/tripleo-config/ceph (instead of /etc/ceph) and set
these paramters explicitly in scenario00{1,4}. This will
result in all Ceph client configuration being done not by
ceph-ansible but by the new tripleo-ceph-client role from
tripleo-ansible.
Add the CephClient service to all Controller* roles which will
use Ceph. The service could have always been there as there are
Ceph clients on the these controllers, but it was not because
ceph-ansible configured clients as a side effect. With new
CephConfigPath default they no longer overlap so the service
is required.
Add support for CephExternalMultiConfig via tripleo-ceph-client
by looping on the contents of the CephExternalMultiConfig list
and passing each map as the dcn variable while including the
tripleo-ceph-client role each time.
