Checkmk Werk 13049: RESTAPI: require accept header

ID: 13049 Title: RESTAPI: require accept header Component: Core & setup Level: 1 Class: New feature Version: 2.1.0i1 In previous version the accept header of the HTTP-request was completely ignored. With this werk the accept header is obligatory. If no or a wrong accept header is provided an error with a 406 status code will be returned. For most requests this means you have to provide the follwing header line: <tt>Accept: application/json</tt> For some other requests different accept headers may be required. All headers are documented in the official rest-api documentation. For example when downloading the agent binary the following header is required: <tt>Accept: application/octet-stream</tt>
