Make streaming API faster

[tmaiaroto]

The queries made using the streaming API endpoints (data by date range) comes in too slow. Queries may need to be executed concurrently (with a limit) and glued together in the right order if performance can't be found otherwise.

Additionally, the front-end dashboard may need to do a better job caching results so that it can simply make requests for any missing data. For example, it might only need one or two days of results in a month because it already cached the other 28 days. Multiple requests could even be made to fill in the "gaps" of missing data.

-- This was with regard to Postgres. It needs to be re-built and re-tested using InfluxDB. The thinking was the concurrently make multiple queries to Postgres and/or to utilize partitioning.
