    Description

      Based on the comments on YARN-3134 and YARN-3411, we need to change the data model to restrict the data type of info/config/metric section.

      1. Info: the value could be all kinds object that is able to be serialized/deserialized by jackson.

      2. Config: the value will always be assumed as String.

      3. Metric: single data or time series value have to be number for aggregation.

      Other than that, info/start time/finish time of metric seem not to be necessary for storage. They should be removed.
