Api for getting stats from aggregated orders

[akhlopiachyi]

It is necessary to have api for aggregate orders
Output values should be ready to use with average on period, max, min, volume

[calj]

A good design is to duplicate orders in AMQP queues and have workers aggregating those queues in average, max, min, volume per periods (10m, 15m, hourly, daily, ...)

Redis is a good candidate to store the aggregated data plots.
