The flux query controller was updated to include a Shutdown method a
while ago. Explicitly handle query controller creation and shutdown
where applicable.
In influxd, this ensures that outstanding queries are handled before the
process dies. In tests, this ensures that query controller goroutines
aren't leaked, which drastically simplifies reading full stack traces.
This change also registers query controller metrics with the prometheus
registry in influxd.
- Brought over enterprise's QueryLogReader, with small adjustments
- Time filters are for the run's ScheduledFor field, per spec
- Adjusted run log timestamps for consistent formatting:
- ScheduledFor is RFC3339 because it's a whole-second timestamp
- StartedAt, FinishedAt use RFC3339Nano for high precision
- Several test adjustments to use relative time, for easier integration
with storage retention
