Create new task to build dvla file.

Browse Source 
This will transform each notification in a job to a row in a file.
The file is then uploaded to S3.
The files will later be aggregated by the notifications-ftp app to send to dvla.

The method to upload the file to S3 should be pulled into notifications-utils package.
It is the same method used in notifications-admin.
