> Storage plugin for OpenTSDB
> The plugin uses REST API to work with TSDB. 
> Expected queries are listed below:
> SELECT * FROM openTSDB.`warp.speed.test`;
> Return all elements from warp.speed.test table with default aggregator SUM
> SELECT * FROM openTSDB.`(metric=warp.speed.test)`;
> Return all elements from (metric=warp.speed.test) table as a previous query, but with
alternative FROM syntax
> SELECT * FROM openTSDB.`(metric=warp.speed.test, aggregator=avg)`;
> Return all elements from warp.speed.test table, but with the custom aggregator
> SELECT `timestamp`, sum(`aggregated value`) FROM openTSDB.`(metric=warp.speed.test, aggregator=avg)`
GROUP BY `timestamp`;
> Return aggregated and grouped value by standard drill functions from warp.speed.test
table, but with the custom aggregator
> SELECT * FROM openTSDB.`(metric=warp.speed.test, downsample=5m-avg)`
> Return data limited by downsample
