Multiple Ceph Cluster Metrics not compatible with current dashboards/alert rules

[linwalth]

The dashboards/alert rules that are being shipped with grafana / provided by https://github.com/osism/kolla-operations are not compatible with the use and scrape of multiple ceph clusters, as the dashboards are not created to work with multiple clusters and the alertrules for e.g. osds and pools break because the conflicting pool IDs from the two sources create rule evaluation failures.
