Gian Merlino 16ef513c7d SQL: Add context and contextual functions to planner. (#3919) 
* SQL: Add context and contextual functions to planner.

Added support for context parameters specified as JDBC connection properties
or a JSON object for SQL-over-JSON-over-HTTP.

Also added features that depend on context functionality:

- Added CURRENT_DATE, CURRENT_TIME, CURRENT_TIMESTAMP functions.
- Added support for time zones other than UTC via a "timeZone" context.
- Pass down query context to Druid queries too.

Also some bug fixes:

- Fix DATE handling, it was largely done incorrectly before.
- Fix CAST(__time TO DATE) which should do a floor-to-day.
- Fix non-equality comparisons to FLOOR(__time TO X).
- Fix maxQueryCount property.

* Pass down context to nested queries too.
