• Allow arbitrary prometheus range queres (update prometheusResponse)
• Allow usage of more than one slo checker
• Update the json which send to the python slo checker
• refactoring
• Update CRDs in order to set the query string as an dedicated parameter for a slo checker
• Update exisiting python slo checker in order to use the new JSON format (handled in !185 (merged))
