dma: New package

Fixes #10953

Fixes #10954
	The dma-queue-flush.timer will execute the corresponding service
	file every hour to call dma and send out all mails. The
	dma-cleanup-spool.timer is used to periodly call the service
	file for cleaning up the DMA spooler directory.

	Both timer files will be enabled during installation of the dma package.

Fixes #10955
	This dma-cleanup-spool script cleans up the spool directory from
	DMA mail service after defined period of time. Otherwise the spool
	dir may be flooded.
