Implement the use of scalar functions inside aggregate functions. This allows for complex expressions inside aggregations, with or without GROUBY as well as with or without a HAVING clause. e.g.: ``` SELECT MAX(CASE WHEN a IS NULL then -1 ELSE abs(a * 10) + 1 END) AS max, b FROM test GROUP BY b HAVING MAX(CASE WHEN a IS NULL then -1 ELSE abs(a * 10) + 1 END) > 5 ``` Scalar functions are still not allowed for `KURTOSIS` and `SKEWNESS` as this is currently not implemented on the ElasticSearch side. Fixes: elastic#29980 Fixes: elastic#36865 Fixes: elastic#37271 (cherry picked from commit 506d1be)
