Remove usage of local config object in Vitrage services and tests. Instead, it's been replaced with the global CONF object. The structure of the code becomes more like in other OpenStack projects. Also, this change provides an opportunity to introduce migrations and tests for them. Story: 2004059 Task: 27065 Change-Id: I37544a350adf8ca38a6fc4ff5d0fd96e38a3f922
