Gian Merlino e86859b228 SQL support for nested groupBys. (#3806) 
* SQL support for nested groupBys.

Allows, for example, doing exact count distinct by writing:

  SELECT COUNT(*) FROM (SELECT DISTINCT col FROM druid.foo)

Contrast with approximate count distinct, which is:

  SELECT COUNT(DISTINCT col) FROM druid.foo

* Add deeply-nested groupBy docs, tests, and maxQueryCount config.

* Extract magic constants into statics.

* Rework rules to put preconditions in the "matches" method.
