[filipecosta90]

overall description

solves #109 [fix] fixed cpu-max-all-* for influx. [add] added influxql to --print-responses option within query runner

If you guys compare timescale's and influx's results for cpu-max-all-1 and cpu-max-all-8 queries, you will notice that there is a wrong group by time clause on influx ( group by time(1m) should be group by time(1h). The changes in this PR fix the issue and improvement the resultset output for influx ( so that we can easily check this type of error.

Great catch -- looks like the tests need to be slightly updated.
