/**
 * Parses a TsQuery out of request, divides into subqueries, and writes result
 * from openTsdb//from   w  ww.  j  av  a  2 s .c o m
 *
 * Format for GET request:
 * start - required start time of query
 * end - optional end time of query, if not provided will use current time as end
 * x - expression (functions + metrics)
 * m - metrics only - no functions, [aggregator]:[optional_downsampling]:metric{optional tags}
 * either x or m must be provided, otherwise nothing to query!
 * ms - optional for millisecond resolution
 * padding - optional pad front of value's with 0's
 *
 *example:
 * /api/query?start=1436910725795&x=abs(sum:1m-avg:tcollector.collector.lines_received)"
 * @param request
 * @param response
 * @throws IOException
