[BROKEN COMMIT]

This code leverages the new `types.isType` functionality introduced in the flux language (https://github.com/influxdata/flux/issues/2159)

This code will fix https://github.com/AnalogJ/scrutiny/issues/22 and all related issues.

Unfortunately this code is broken because the influxdb go client library does not correctly handle import statments in the task defintion.
