Enhancement: config for removing archived DataObjects

[wernerkrauss]

in SS5 (V 3.1.1 of this module), running sake dev/tasks/TruncateVersionsTask archived=1 deletes all archived DataObjects in every subclass of DataObject.

I'd like to switch this off by default and configure it for the classes where I want to delete the archived records.

Happy to provide a PR

Hi @wernerkrauss. I'm not in support for changing the default behavior of the module, however adding an optional configuration to limit it to specific DataObjects would be OK. I'm happy for you to provide a PR.

Some notes/thoughts:

• the config should be a yaml array of classnames
• no error if a non-existent classname is used (or is not Versioned), as this will allow you to add a single value of - false or something to disable by default (achieve what you were describing)
