cca0d9f7d7
Implements base method as well as some basic implementations to retrieve time series metrics. Ceilometer can not be supported as API documentation has been unavailable. Grafana will be supported in follow-up patch. Partially Implements: blueprint time-series-framework Change-Id: I55414093324c8cff379b28f5b855f41a9265c2d3
