search: Import query clicks from airflow 1

Direct port of the query clicks hql jobs from airflow 1. Have manually verified that the rendered hql is equivalent in airflow 1 and 2.

The test suite in airflow 1 was able to verify that these rendered hql statements were valid hql, by passing them through the spark sql parser. Unfortunately we don't have anything here that can do the validation so only manually testing was done to verify correctness, no automated validation is performed.
