Add migration DAG for CX report
Phab ticket: T356424
Migrate CX report from ReportUpdater to an Airflow DAG.
Original report updater query location: analytics-reportupdater-queries/cx/
This report directly populates a Hive table amire80.cx_abuse_filter_daily located in /user/amire80/data/cx_abuse_filter_daily on HDFS.
The HQL file referenced by this DAG is located in analytics-refinery/hql/reportupdater_queries/cx/
Gerrit review for the HQL file: https://gerrit.wikimedia.org/r/c/analytics/refinery/+/1003928
