Checkmk Werk 11484: Management Board: Remove explicit check plugins

ID: 11484 Title: Management Board: Remove explicit check plugins Component: Checks & agents Level: 1 Class: Bug fix Version: 2.0.0i1 The only difference of check plugins for Management Boards was the resulting service description. In case, the plugin was related to a Management Board, the prefix "Management Interface:" was set by the check plugin. As the discovery now handles this scenario, the explicit check plugins are not needed any more. Note: If you use local checks that use plugin sections that have an equivalent Management Board section, changes on that checks also affect the processing of the Management Board plugin section, e.g. <<<snmp_info>>> on <<<mgmt_snmp_info>>>.
