Simplify ceph.conf generation
Simplify ceph.conf generation

Since the approach to creating a ceph.conf file has changed, and now
no-longer relies on assembling config file fragments in /etc/ceph/ceph.d
we can avoid the conf_overrides rendering on the local host and skip out
the tasks related to that, instead using just the config_template task
to configure the file directly.
