Checkmk Werk 13730: check_temperature: Make 'unique_name' and 'value_store' optional, but both are needed for trend computation

ID: 13730 Title: check_temperature: Make 'unique_name' and 'value_store' optional, but both are needed for trend computation Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 Since Checkmk version 2.1.0 the check_temperature function required {{unique_name}} and {{value_store}}. Both are only needed for trend computation. Now {{unique_name}} and {{value_store}} are optional again. The check engine raises a ValueError if only one of both are set.
