Checkmk Werk 8845: Web-API: Prevent adding wrong encoded labels to hosts / rulesets

ID: 8845 Title: Web-API: Prevent adding wrong encoded labels to hosts / rulesets Component: WATO Level: 1 Class: Bug fix Version: 1.7.0i1 In previous 1.6 releases the Web API did not validate the labels that could e.g. be added to hosts strictly enough. When using "python" as "request_format" this could result in a broken configuration, leading to exceptions in several places of the GUI. The Web API now ensures the received labes are all unicode strings as Checkmk expects.
