For now, we must run the container with UID 0 and privileged for
multiple reasons:
* the rook binary writes ceph config to /var/lib/rook which is owned by
root
* it's difficult to use /etc/ceph since it will conflict with the
rook-ceph-override configmap AND is also owned by root since it's a
mounted configmap.
* using /etc/ceph might be possible but has other issues with rook's
exec package since the ceph config is built from /var/lib/rook
