* Rename selectStatement to buildInfluxQLQuery
* Moved `influxql/select` to `utils/influxql`
* Replace `buildQuery` with `buildInfluxQLQuery` util function
* Retain GROUP BY clause when saving cell query
* Revert "Replace `buildQuery` with `buildInfluxQLQuery` util function"
This reverts commit d932d99bfa0de54d07be4b42cc13d1b34fbe950b.
* Build DashboardCell queries with buildInfluxQLQuery util
Retain old LayouRenderer.buildQuery functionality for
canned dashboards, and anything else that isn’t using
the queryConfig schema. Rename this function to make
it clear that it is legacy behavior, and that it
should not be a dependency of any new code.
* Update CHANGELOG
