[Enhancement] Add a properties to configure max-archive-size option

[baran81]

Hi.
We have some big database to backup and we got some issue with ephemeral storage usage.
We was able to manage the useg setting max-archive-size, but to do so we have tu use the additionalCommandArgs property.

to polish the yaml would be great to have a property in DataBackupConfiguration ¶ and some documentation line about Ephemeral storage consumption and parameters like "jobs".
