dataSeries

This represents a series of related data gathered for a metric. A series may also contain sub-DataSeriess when multiple dimensions are selected as the pivot during the query. For example, if a metric query is pivoted by instance and op-type, there will be a DataSeries for each of the instances and the aggregated data. Each DataSeries is further broken down into sub-series for each op-type and its corresponding data. Logically, it will look like:

server1: data [3 4 5]
- add: data [1 0 3]
- delete: data [1 3 0]
- modify: data [1 1 2]
server2: data [5 2 4]
- add: data [0 1 1]
- delete: data [3 1 0]
- modify: data [2 0 3]
