We changed primary key for bucket_bandwidth_rollups table. Now we
need to do some cleanup in places like structs, sorting methods or SQL
queries.

Sorting by primary key before inserting data into DB is fixed.
Earlier we were sorting input slice of BucketBandwidthRollup but then
we were putting all entries into map to rollup input data. Iteration
over map with a range loop doesn't guarantee any specific order so we
were loosing sorted order when we were creating with this map slices to
use with DB insert.
New code is also using map but when map is full its sorting map keys
separately and iterates over them to get data from map.
