This refactors everything to generate and use a flux AST when
transpiling an influxql query. This also updates the spectests so they
use flux instead of writing out the AST and compare the resulting
AST's.
We reorganized the functions in flux to have the structure:
/functions
/inputs
/transformations
/outputs
this PR catches up platform to work with the new package layout.
As a separate refactoring issue, we should discuss:
from(bucket: ) should migrate from flux --> platform
to_http and to_kafka should migrate from platform --> flux
The now time is stamped by the influxql transpiler and used inside of
the actual query. It will result in more accuracy if we take the
timestamp we have created and send it as part of the spec to queryd
rather than force ourselves to ensure absolute times exist everywhere.
