Checkmk Werk 13955: Add graph data endpoint to the REST API

ID: 13955 Title: Add graph data endpoint to the REST API Component: REST API Level: 1 Class: New feature Version: 2.2.0i1 The REST API now has endpoints for querying graph data. They are analogous to the Web API endpoint. If you have any calls to ".../cmk/check_mk/webapi.py?action=get_graph...", please use the REST endpoint ("/domain-types/graph/actions/get_*_graph/invoke") instead. Please note that the request and response schemas differ from the Web API and any client code should be adjusted accordingly. Further details about the schemas can be found in the documentation of respective endpoints
