Per the discussion on ML, I proposed to create an .asf.yaml file for customizing email notification. Please take a look, thanks! @gszadovszky @shangxinli @pitrou @emkornfield

Thanks @gszadovszky @pitrou! I'll merge it to see what happens. If it works as expected, I'll create a PR for parquet-format as well.

@gszadovszky @julienledem @shangxinli Do you have the permission to change the notification rule here (https://issues.apache.org/jira/plugins/servlet/project-config/PARQUET/notifications)? It sends all JIRA notifications to dev@ ML. It would be good to send them to issues@ ML instead.
