I'm thinking now that it'd be better if the module collected metrics from all OSs instead of having two different metrics, as one metricbeat can be collecting from a docker server in a different OS. |

Docker stats use a different data structure for blkio stats in Windows, the main difference is that in posix systems (Linux at least) stats are separated by device by Major/Minor (lists of BlkioStatsEntry), and in Windows they are directly summarized by reads and writes, by operations and volume (StorageStats). This change counts the metrics of both data structures and aggregates the result. Fixes elastic#6815 (cherry picked from commit 63f25a4)
