Checkmk Werk 12284: Drop legacy "Use unsafe legacy encoding" setting

ID: 12284 Title: Drop legacy "Use unsafe legacy encoding" setting Component: Setup Level: 1 Class: Bug fix Version: 2.0.0b9 This setting has been deprecated before Checkmk 1.4 and has now been finally removed. It was only kept for compatibility with pre 1.4 sites in distributed setups which is not relevant anymore these days.
