Check_MK Werk 2848: Fixed cleanup of old autocheck files of cluster hosts

ID: 2848 Title: Fixed cleanup of old autocheck files of cluster hosts Component: Core & Setup Level: 1 Class: Bug Fix Version: 1.2.7i4 The autocheck entries of clustered services were stored in [cluster].mk autocheck files in past versions. Current versions are now storing the autochecks in the node specific files. The old [cluster].mk files were not cleaned up during discovery leading into duplicate autochecks entries. As these files were never updated again, they could result in unwanted services on the cluster hosts. This could be fixed manually by removing the [cluster].mk autocheck files via command line. The current version is now cleaning up the files during discovery.
