[openstack-exporter-k8s] Correct the Ceph dectect variable in dashboard

Browse Source 
The query for `Ceph Shared Storage` variable returned both values 0 and 1 when a shared Ceph config is detected, since the `or` operator in promql returns both values when evaluating between two terms that both have data.
This can be simply fixed by wrapping a max() around the expression.
