[Operator] Grafana dashboard does not differentiate between the caches with same names

The queries for cache visualization do not take into account namespace or the job they are supposed to take the value from. The query retrieves the metric for the cache from all the monitored clusters and displays whatever is the maximum value between them:

max({__name__=~"vendor_cache_manager_default_cache_($caches)_cluster_cache_stats_number_of_entries"})
