Gian Merlino 2ce8123bdb Move scan-query from a contrib extension into core. (#4751)
* Move scan-query from a contrib extension into core.

Based on a proposal at: https://groups.google.com/d/topic/druid-development/ME_OatUDnbk/discussion

This patch also adds support for virtual columns to the Scan query,
and updates Druid SQL to use Scan instead of Select.

This patch also makes some behavioral changes to handling of the __time
column. In particular, it is now is returned as "__time" rather than
"timestamp"; it is no longer included if you do not specifically ask for
it in your "columns"; and it is returned as a long rather than a string.

Users can revert time handling to the legacy extension behavior by
setting "legacy" : true in their queries, or setting the property
druid.query.scan.legacy = true. This is meant to provide a migration
path for users that were formerly using the contrib extension.

* Adjustments from review.

* Add back Select query.

* Adjust SQL docs.

* Restore SelectQuery link.

Andy Sloane 706747cc8c Fix for sort order in select/topN query cache (#4766)
When historical caching is enabled, and a select or topN query is
issued, and then a following query with "descending": true is set, the
cached query returns the ascending result (or vice versa), often
resulting in invalid paging identifiers.

The CacheKey for these queries doesn't include the "descending" flag;
this change adds it, and fixes the problem.
