Werk #12352: Allow to disable management board checks in Disabled checks

Due to a regression no check plugins could be disabled for management interfaces from version 2.0.0i1 to 2.0.0.

Users were unable to edit existing rules if they included check plugins starting with mgmt_, and to create new rules to disable check plugins discovered on management boards (unless they were separate Checkmk hosts).

You can now disable check plugins for regular hosts and management boards separately in the ruleset "Disabled checks".

Previously configured rules will continue to work, and can be edited.
