|Title||Fixed "Clustered services for overlapping clusters" rule while checking|

Normally each node is part of a single cluster host in Check_MK. Using the ruleset Clustered services for overlapping clusters you can assign services found on a node to different independent cluster hosts, so called overlapping clusters. This was unregarded while executing clustered services checks on the related clusters. This may result in wrong check results.
Example: Each of the two clusters cluster1 and cluster2 has the nodes node1 and node2. On each node we have discovered a process Process ABC. Within the ruleset Clustered services for overlapping clusters we assign the service Process ABC from node node1 to cluster1.
Now the service Process ABC which is assigned ot the cluster cluster1 processes the data of both nodes and may return a wrong check result in the moment where node1 AND node2 have data for Process ABC.
