Checkmk Werk 15406: Renaming of hosts: Handle TLS agent registrations correctly

ID: 15406 Title: Renaming of hosts: Handle TLS agent registrations correctly Component: setup Level: 1 Class: Bug fix Version: 2.3.0b1 When renaming hosts which were registered for TLS-encrypted agent communication, Checkmk ran into the following error: C+: TypeError: '<' not supported between instances of 'tuple' and 'str' C-: Furthermore, in distributed setups, renaming TLS-registered hosts which were monitored on remote sites lead to a loss of registration, which prevented any further agent communication until the affected hosts were re-registered.
